In brief: Not withdrawal
Periactin (cyproheptadine hydrochloride) (cyproheptidine) makes you sleepy.
Sometimes it makes you hungry but it's not habit-forming or addictive. If you feel more alert, less drowsy, have more energy, and decreased appetite that's just the effects of this classical antihistamine wearing off.
