Goemon:
I wanted to ask if there is any body that know what could be the risk from taking periactin for a long time?
I think that goes to all medicines - if you take something for a long time - then your body shifts its balance towards this. I.e. you're taking hormones - and after a while if you don't stop - your body will stop producing that hormone for you to restore hormone balance when its supplied externally.
For cyproheptadine you can just google and read all side effects. They are nasty, because its just a 1st generation antihistamine.
But anyway sideeffects tend to diminish if you're taking continiously, including hunger - thats your body adapts.
So if you're really want to use it - I'd suggest you do it at least in short courses. Like you're boosting hunger, you feast, then when effect weakens and you adapt - then stop and give it a rest for idk... a month or something...
