It really really is. It's the best thing about all of it.
After I gained weight my hunger started to really bother me more- I think it's hunger hormones from all the extra fat cells- my stomach would hurt bad, headaches would happen easily, I would get nausea from hunger, and so on. Now I feel so resilient.
If you end up with worse side effects than me, I would definitely recommend treating them aggressively. Fiber supplements, nausea pills, diet changes to reduce gas, etc. Most of the bad side effects people get are actually like... Pretty normal basic OTC stomach upset kind of stuff.
I also had a weird side effect for like 3 days after one of the dose increases, where my skin was sort of sensitive in an annoying way, kinda like having a sunburn. Never came back though.
Yeah it's pretty cheap in other countries. They made a sleep apnea version as a pretty transparent workaround to force insurance to cover it for people without diabetes. The manufacturer coupons also really help. Insurance can be very fucking annoying about it but so far they have paid for it. At one point they fucked me and delayed it several days and I had to pay full price and get reimbursed via check a few weeks later.
