I have taken paxil 2 - 3 years probably, started out taking 12.5 miligrams but during the last year and a half increased to 20.m.g. I have terrible night sweats, clinch my teeth really bad, have dreams that are "hair raising", not frightening all the time but just wake you up feeling strange.I've gained weight but that may not be the paxil, I have a real urge to eat sweets that I've never had before the last year or so. I have very hard to explain popping in my ears when I'm laying down. It affects my hearing and I even see flashes when I'm trying to go to sleep. I have miagraines and attribute some of this to that. However this did not happen prior to taking the paxil and I wonder if other people have the same symptoms. I'm in the process of stopping taking this drug and have just about gotten off it. How long will it be before its out of my system? Does anyone have these "strange feelings with their ears and head?"
