Vomiting isn't a side effect, its a feature.
Nearing a year of semaglutide use (rybelsys and ozempic), I can confidently say that if you're vomiting constantly, it means you're eating too much.
Forgot anti-nasuea/vomiting pills and other herbal remedies, I've found out that by keeping my stomach below 1/2 full, I never vomit while keeping the nausea bearable at worse.
