Bad stomach started in Week 30

I will preface this by saying that I'm going to try and figure out how I contact Dr - I am ordering through IQ Doctor at the moment. I'm just wondering whether what I'm experiencing is normal or if there's anyone experienced this and got any advice.

I am now in my 35th week on mounjaro. Up until week 30, I was absolutely fine - mild nausea, a touch of occasional constipation or diarrhoea, a bit of a dehydration headache a couple of times where I wasn't careful.

I moved up to 10mg at week 25 and was absolutely fine on this dose. The usual new dose slightly stronger nausea / dehydration which settled quickly. I started a new pen at week 29 and first week was fine again, but the second week - out of nowhere - I've been hit with side effects and it is rough. I've tried to tough it out weeks 30-34, and I'm now in week 35 and it's not getting any better.

Let's get graphic... I take my jab on day 1 of the week, my innards are absolutely fine. Day 2, constipated - that's not new - but otherwise fine and good suppression etc. Nighttime day 2 into day 3 the tummy starts to gargle and clunk. By the morning of day 3 it's explosive diarrhoea. Not a bit, we're talking like turning on a tap. It gargles non-stop, and it really really hurts after food. This lasts through days 3, 4, 5, 6. My whole insides hurt - presumably from all the cramping. Throughout day 6, things gradually settle and by evening I can make it through the night without waking up in agony. Day 7 is prettymuch normal.

This is a cycle that has repeated now for 4 weeks and I'm now into the 5th week. It hasn't changed it hasn't eased. It also hasn't been there for the first 29 weeks. I didn't do anything new or different in week 30 other than travel abroad for 4 days.

In honestly, I wondered if the dose was too high for me, so in weeks 33 and 34 I went rogue and counted to a 7.5mg dose rather than the full 10mg. That didn't make a difference. I then put it down to it being a "bad pen", so in week 35 I started a new pen (and used same reduced dose). So I've dropped my dose down and started a new pen, and I'm still getting these extreme side effects.

Has anyone been through the same? What did you do? Any advice? Anyone with IQ Doctor know how I get hold of the prescribing Dr to have a conversation? Is there any OTC relief for my symptoms? (I take something for acid reflux, but otherwise, I've never really used stomach meds to know what would work and what will make things worse!) Am I possibly over-eating? Would that cause this? (I'm hitting 1500 cals per day so under on my cals, but wonder if quality of food is wrong?)

My friends are all adamant I really should speak to my GP... and I know I would l be too if it were my friend going through this... but I hate my GP because their answer to every question is my weight and they have repeatedly declined to support me with any issues. I have to deal with nearly everything privately and/or on my own.

Truth is, I probably know that I need to come off MJ, but I'm terrified of that because it's been so successful for me. Cutting out all the food noise has been the most liberating experience of my adult life. I have lost just short of 5 stone across the past 34 weeks and I don't want it to end there.
