Mounjaro 5mg back to 2.5mg advice!

Hi,
So I started the jabs around 7 weeks ago, felt fine on 2.5mg had the odd evening after the jab of feeling a little nauseous but nothing too bad and wouldn’t be every week.. then the 4th week felt none at all so decided to go up to the 5mg pen.

First 2 weeks fine, had a bad headache for two days after my jab but kind of dealt with it & then after my 3rd which was last week I had the worst headache for about 3 days followed by constant nausea, cannot shake it. Feel awful, haven’t been sick but feel so sick 24/7!
I threw away my last 5mg pen as couldn’t bare the thought of ever doing it again.
I’ve now ordered the next months at 2.5mg.. I’m still feeling awful to be honest and I’m debating whether to do it this week at 2.5 or give myself a weeks break? Any advice would be really appreciated ?
Will I feel better on 2.5 or if I inject whilst still feeling this rotten am I setting myself up for longer suffering?! I’m so close to my target weight I don’t know what to do.
had anyone else had similar experiences?

I can’t say I’ve had this experience, but do you feel like you’re drinking enough water? It’s something I struggle with but I find it helps.

If I’m honest, I definitely don’t drink enough water, not nearly enough.
I’ll try and uptake my water to see if it helps. Thanks

Honestly drink more, was my first thought that you're not drinking enough.

Also track what you eat. I feel awful about 3-4 hours after I eat chocolate. Other sweets things are ok, weirdly.

I had this when I went up to 5, first week fine, second week was horrendous with constant indigestion, constipation, I vomited a couple of times and was also a bit dizzy.

I was drinking more than 2litres of water a day and was not dehydrated.

I decided to stop for a week and then took a 2.5 dose from the 5 pen (30 clicks). I kept up the healthy eating and was drinking plenty and still lost weight as it stays in your system for a while, no suppression but I have good willpower when needed.

I ordered and have been on the 2.5 dose since and apart from the odd indigestion I have continued to lose 2-3lbs per week and have lost nearly 3 stone since I started in December.

Thank you so much for your replies.
@stopringingme that’s so good to know!
I would usually do my next jab tomorrow but I’m going to wait until the weekend and do a 2.5 as I’ve ordered that dose now and praying I’ll have no bad side effects and continue to lose as you have. I’ve only got about 10lbs until my goal weight so after this lot I’m done and honestly can’t wait to be done now. I know I’ve had an easy ride compared to some but that week of constant nausea has really put me off, I can deal with most things but sickness I can’t.
good luck to everyone on their journeys!
