I hope it’s okay to start a new thread as we are getting dangerously close to the end of thread 1

My current stats are

MJ 2.5mg just taken dose three
planning on staying on 2.5mg for my next pen
SW: 13 stone 9.4lbs
Week 1: lost 11 lbs
Week 2: lost 3 lbs
Total weightloss: 1 stone (a small jack russel terrier)
GW: 9 stone 7

We have some newbies joining mid month so let’s cheer them on - we’ve got this ladies!

Hi Jan jabbers!

I come here to offer advice I wish i was given when i started on MJ in July 2025.
Firstly, no regrets! Lost over 3 stone and feel more like myself again. Now i'm starting to taper off very slowly as I try to increase my exercise (i've done none!) and rely less on the appetite suppression to lose the final 2 stone.

Secondly, hair loss does happen around the 3-4 month mark for many of us but not all. It scary and it can make you panic but please be assured, it's a natural reaction to significant or sustained weight loss and calorie deficit. It will stop and it will grow back. Also, for many of us, no one else even notices.

The advice i wish i was given at the start of my MJ journey was to make sure you keep your protein up there. If you struggle with food quantity many of us decided to use the MyProtein Whey Clear (Not affiliated at all). It's low calorie and is like drinking a cup of diluted fruit juice (think iced peach tea texture and strength). Also, take your multi-vitamins! All this will likely help and I wish I had known.

Anywho, there's my two cents. Best of luck to you all!
I'm happy to answer any questions if you have them

xx

Edited

Thanks for the tips.

I'm not getting enough protein so will be getting the Myprotien Whey Clear. Any suggestions on flavours?

Hi. I am so sorry
Have you been to the gp to rule out if you are low in iron? As that can make your hair fall out too
Sorry to say but no, it hasn't stopped falling out. It is starting to grow now though x

Yes I’ve had a blood test and I’m all good. So yours carried on falling out even after you stopped jabbing?

I did the mixed box to trial lots of them and found the only ones i liked were:
Peach tea
Vimto
Raspberry Lemonade

A lot of people swear by the clear flavourless as well but I haven't tried it.

Yes but I am incredibly low in iron
I drink lots of protein shakes, quite a lot in the Asda sale just now
Aldi also have yoghurt drinks for 99p, protein pancakes for 99p, protein milk for 99p all of which is delicious (and I'm fussy)
I take a supplement which has helped my hair grow back quicker

Seems I was right to worry about my digestion! I have a very bad stomach (day 3 after first dose) and so have had to stay home from work. I am holding a tiny bit of hope that it’s a bug and not Mounjaro related as DH said he also doesn’t feel great today.
Anyone that has had d&v - did you manage to keep eating at all? I feel like I need something for energy but - TMI - it’s going straight through so I’m not sure there’s any point?!

It’s great to get tips from those further ahead - thanks for sharing!

I was similar. I did try to eat small amounts of very bland food (toast, crackers), but honestly there came a point where I just had to wait for it to run its course. I found forcing food when my stomach clearly wasn’t ready didn’t really help.

If it is d&v, hydration is the priority. I found I could tolerate small, frequent sips rather than big drinks. I think it's okay to ease off briefly and listen to your body.

It could still be a bug, especially if your DH isn’t feeling great too, so hopefully that’s the case and it passes quickly.

Hope you feel better soon.

Boyandgirlanddone · 19/01/2026 16:25

Hi all, I’m due to take my 3rd jab tonight.
SW 13st and a bit
CW 12st 6
GW 11st
No real side effects apart from some slight nausea and also completely bonkers dreams the night after I inject. Anyone else?!
Im currently on the lowest dose of WG and it’s working like a dream. It’s totally turned off the food noise and I’m eating the way my mum and sister always have. Like little birds. Which always made me feel like an absolute pig! Such a strange feeling.
I bought 3 months worth, planning to increase each month but if injections 3 & 4 work as well as 1 & 2 I may attempt the half doses.

FrothyCothy · 19/01/2026 16:48

Well I needn’t have worried about Numan - it’s been dispatched already! £29, doubt I’ll ever get it cheaper than that!

AddUpToNothing · 19/01/2026 17:18

I have just ordered my second pen as well as some syringes and alcohol wipes. I decided to buy the 5mg as there wasn’t a massive price difference and see how I feel once I’ve had the 5th dose as to whether I take the 5mg or short dose and continue on 2.5mg.

intentionals · 19/01/2026 18:09

Have ordered my next pen at 5mg. Boots asked some questions and I confirmed all fine except for some digestive issues if I overeat or have caffeine. I also explained that on days five and six I am feeling quite hungry again. I think the “standard” is 5mg so will see how this week and next week go and then move up. Then want to stay on 5mg as long as possible.

worried about getting more side effects etc but guess I will see what happens

i have had a lot of digestive stuff - I figured out some triggers through in the first week and now it seems better. Are a bit too much yesterday which started it all off again…

i wasn’t even hungry yesterday - just felt a lot of pressure in a lunch situation to eat so am annoyed at myself!

Whatstfpoint · 19/01/2026 18:42

Yeah im getting a dull stomach ache. I think it's certain foods. I had muesli, Yogurt, fruit and almonds for lunch plus carrots and nothing. Then later I had an apple and I have this dull ache and incredible feeling of fullness an hr later. I think it's bloating. Can't even eat apples on wegovy.

How did you get such a good deal if you don’t mind me asking?

sunnysunshinebear · 19/01/2026 19:00

No idea! It was listed on igovy as the cheapest place for 0.25 Wegovy - assume it’s a new customer offer and will quadruple in price when I go back for 0.5 for the following month.

MJ2026 · 19/01/2026 20:10

Hi all. Just looking for advice. I started MJ two weeks ago. About to jab 3 on Wednesday. I have had zero side effects and am finding I’m not eating as much as I normally would. I am using the Nutria check App to track calories and am consuming average 1500 cals per day. All has been well.. until today. Food noise has came back. I’m now trying to decide if this means when I get my next dose I should go to 5mg. I think I have scared myself about moving up as I have seen on TkTk so many others complaining about the side effects of moving up. Is moving up the next step for me? Alternatively I have seen ‘slip dosing’ where you take 2.5 and a few days later another 2.5 so basically 5mg just split over days. I really want this to work and I notice my stomach area is smaller and clothes are loser. I’m only weighing monthly due to my MH so don’t know what this means in terms of scale losses. But I’m just looking for reassurance it will be ok if I move up. Thanks everyone

mendandmakedo · 19/01/2026 20:16

Are you keeping hydrated, drinking plenty of water? Its really hard to decide isn't it. Interested as well to see what everyone else thinks.²

TwistedOrange · 19/01/2026 20:26

Well I went for it tonight, decided not to delay any further and did my first wegovy jab. I feel a bit nervous and a bit excited, and hopeful that it will work for me.

Bear in mind, mj has a half life of 5 days. So you may notice food noise coming back. But also its important to keep going and use willpower, you need to change your habits to help you for when you come off the injections
I had no side effects going up to 5mg last year
I had diarrhoea and sickness and sulpher burps on 2.5 for 4 days then no side effects at all for any further dose

blackandwhitefluffycat · 19/01/2026 20:30

Well my 5mg has arrived so decision made! I still have two doses of 2.5 left (if you include the extra dose). I’ve had no side effects after 3 jabs so I’m hoping it’ll be the same with 5, but hopefully any new ones that appear will just be temporary.

Also I ate what I’m eating now for a month last year (though suffered as I was hungry and had to use lots of willpower!) and lost zero weight so it feels like it’s doing something more than just reducing my appetite - I’ve already lost 13lbs since 1st Jan. So I’m keen to start a ‘therapeutic dose’ to keep it going.

ThisAmusedPoet · 19/01/2026 20:44

Oops, totally missed the start of a new thread and thought it had gone quiet over here!

doing fine still week 2, nothing ground breaking, no bad side effects, but big test coming up at the end of this week … ten days in America on Mounjaro!

I’ve ordered my 5mg jab as I’ll be away when it comes up. From what I’ve read, it’s fine to bring unopened Mounjaro on the plane even if it won’t be in the fridge.

My stats are:
SW 93.3kg
Mounjaro SW 90.2kg
MJ jab 1: 87.5 kg
total lost: -5.8kg

Thanks for getting back to me notcomfortable I am drinking 3 litres of water eating very clean and well in calorie deficit. It’s just tonight for the first time the noise is back. I’m assuming you mean all doses have the 5 day half life? If so I think that’s my mind made up the split dosing might be the best option for me. Thanks so much again

bookwormcrazy · 19/01/2026 21:42

There’s been a few mentions of the bonus dose. How do you access it?

Howmuchhowlong · 19/01/2026 21:57

I'm 2 days into dose 2 of MJ, I still think about food a lot but not as motivated to go eat it which has to be some form of less food noise! Definitely not huge suppression and hopeful it goes kick in.
I'm tracking calories on MFP and have really reduced carbs, taking a multivitamin and collagen, and aiming for 3 weights/kettlebell sessions a week. All in all feeling more energetic and less sluggish

Tbh I'm debating just stopping again.
I woke up about 1am thinking oh I'm a bit peckish, thought I could just go back to sleep and wait but by 3am my stomach was rumbling
Came downstairs and inhaled 4 chocolate digestives, a sandwich and a yoghurt 😳
I might as well not be on them, I also haven't lost any further weight (Not surprised given what i eat) but it seems pointless, very deflated
