How soon did you start to feel the effects of MJ?

I’m due to start MJ this weekend and I’m curious as to when others started to feel the effects of suppression etc? Also, if you had side effects, when did they kick in?

I’m probably over thinking it and just need to get on with it!! But I’m trying to plan my first dose around being at home in case I encounter any gastro issues.

I took my first dose back in October. I took it about 9pm. By the next morning I felt different but couldn’t explain why - but in a good way!

By day 2/3 I was a different person and for the first time in 20 years I was eating sensibly.

I’m 6st 3lbs down. No side effects except being cold, but I can live with that!

You're not alone in your concerns.
I think we all had them.
I noticed appetite suppression with the first 24 hours.
And I'm 7 weeks in now and touch wood have only had some mild constipation starting the first week.

PrincessHoneysuckle · 16/05/2025 09:21

5 hrs later I had less appetite.Been on it 6 days and lost 2lbs

2025mj · 16/05/2025 10:26

I took my first injection on a Saturday, by early Monday morning I was 💩 so much.
I dont think I ate as clean as I was supposed to. And only really get that side effect when I don't eat clean
I definitely noticed suppression after about a week maybe, but it has never lasted long

I had appetite suppression within a few hours. I've been on it six weeks, am over a stone down, and have had no unpleasant side effects so far. Jab number seven is this evening.

KitsyWitsy · 16/05/2025 10:31

about 2-3 hours. I am definitely a super responder. I've been on it since last September and still nowhere near 15mg.

BarneyOreilly · 16/05/2025 18:59

Suppression kicked in fully on my first day. Could barely eat. I’ve had hardly anything by way of side effects, bit of constipation, some tiredness and feeling cold. That’s about it.

Redlightbulb · 16/05/2025 19:03

I noticed the next day and had a slight sicky feeling.
Not much suppression to begin with & I could eat my full eve meal but half an hour afterwards I felt like I had eaten a Christmas dinner & had a few stomach aches for the first couple of weeks.

Crunchymum · 16/05/2025 19:39

4th jab today. No side effects but no major changes to my appetite and it's all still taking a lot of willpower.

But I'm moving up to the next dose soon and I have had some losses so I'm keeping at it.

ThirdStorm · 16/05/2025 19:44

2 hours! I’m another super responder. I’ve lost 5 stone and did it all on 2.5mg.

ViolaPlains · 16/05/2025 19:51

I didn’t feel any different but the day after I’d taken my first dose I was at a conference and at the morning break I did what I always do - get a coffee and a little packet of biscuits. When I was leaving at the end I was genuinely shocked to see that the biscuits were in my pocket and I hadn’t even thought about them all day. My usual conference practice before MJ was to be early to the coffee queue, get the biscuits/pastries and eat them, and then make sure I got some more before the conference started again. Not eating or thinking about it felt totally alien - in a good way.

A few months in!!

(Sorry!)

PermanentTemporary · 16/05/2025 19:53

A bit of nausea about 36 hours in, headache.

Not much effect at 2.5, in fact I think I gained a tiny amount. 5 was a big change and every step up has brought side effects like sulohur burps, constipation, diarrhoea and vomiting. Better if I don't drink. The vomiting recurs occasionally (like this weekend unfortunately, no alcohol.)

I'm 7 months in, 3 stone down, have been on 15ml for a month or so. I'd like to lose another stone because maintaining is going to be a massive struggle.

Mysticmaiden · 17/05/2025 08:27

7.5 months later, I've had GI symptoms twice only with processed beef and that was during 3rd and 5th pen do not dose related as I've moved up quite a few times, on 12.5mg now amd no side effects at all. I've just had suppression kick in this morning after jabbing Thursday evening. It used to tale 3 days but is getting quicker with stronger doses.

Pretty much this, except I have been on it a lot longer.

The absence of food noise is so liberating.

Only had gastric issues when I overdid it on the holiday AI buffet and bar.

BerfyTigot · 18/05/2025 09:14

I started last Tuesday evening. 36 hours later (Thursday morning) i had vomited and had terrible diarrhoea.

I'm just testing to see if side effects are worse due to caffeine or milk.
