Might retrutide work better for me

I would say it is worth trying, perhaps beginning with a small amount so you are not committed if it does not suit you.

I had to adjust what I eat. I ran into fairly serious problems at the start but removed a lot of dairy and have felt much better since.

Yes, go low and slow because side effects mostly pass. I recall the tirz stomach troubles and they eventually went away for me, though not for everyone, so it is still worth giving tirz more time since it works well.

I have not used Tirz but had similar problems earlier with CagriSema. How is your water and fiber intake, is your diet sorted, and are you moving regularly? A few things like that can add to what you are dealing with before switching medicines. If everything else checks out then maybe try just a small amount of Reta first.

Obviously this is your decision and bodies differ. From what you describe you want fewer or no stomach side effects, no insomnia, food noise kept down, and the smallest dose possible. At low doses of Reta the food noise control might not appear, and after using tirz you could need more than a couple of milligrams to notice anything. Stomach issues could turn out stronger or weaker, only testing will show. Split dosing would be sensible as you are already doing, along with starting low to check tolerance. That approach could bring food noise back and the suppression may feel weaker or different. From what others who tried both report, including myself, Reta often lifts resting heart rate and can cause insomnia even in people who never had it on tirz. If you test it, allow time and patience for it to settle.
