As I have got older I try to stay away from orals most of the year and this is one of the reasons why. They do give instant gratification but I find most come with a bunch of side effects. Some of the stronger ones I can barely eat on so would use shakes or even blend foods to get by.
Have you ever tried Omeprazole when cycling an oral? Although you might not be experiencing some of the full fledged effects on acid reflux, an early sign is often appetite loss. I have zero appetite on any oral... even if i take it for a short span (even a week into Winny and my digestion/appetite feels FUCKED) but if i start omeprazole (nexium or generic, 20mg ED) a week before and everything feels like smooth sailing.
As for an appetite suppressant... metformin is easily the strongest I’ve experienced. If you’re looking for something strictly OTC, a shot glass of apple cider vinegar 15-20 minutes before you’re planning to eat leaves me consuming about a third of what i usually eat. Loose leaf green tea (or a few bags of regular green tea) BEFORE a meal will also destroy hunger. Green tea is very low on the caffeine spectrum but it contains a handful of appetite suppressing components. You just need to brew it stronger.
