As I stated, I originally tried semaglutide with no luck. I didn't try tirzepatide. I've been taking a very low dose of retatrutide - about .5mg twice a week. It seemed to be waning in effectiveness a bit so I upped the dose to 2mg/week for now. It's a night and day difference. Most days I go to the bathroom maybe two times, as opposed to the maybe 5-10 times I would need to unmedicated.

To be clear, this isn't an approved use of the medications (and retatrutide isn't approved at all yet, though it pretty clearly will be). However, they slow down gut motility - and as a bonus for your refusing to eat during week-long work trips, they'd probably at least help with that too, in terms of hunger.
