I've been on Prozac for a couple of years.'originally I was on it for PMDD and anxiety but now on 20 mg a day. I've noticed lately that I have these extreme hunger pains that sometimes last all day. The worst part is no matter how much I eat, the hunger is never satiated. I've read that this could be GERD or acid reflux and not actual hunger. Has anyone else experienced this with Prozac? My doctor doesn't think it's related to the prozac as he says his patients don't gain weight on it.
