Buspar caused me to eat 800 calories per meal. My doctor said it made no sense since buspar supposedly makes you lose weight. I had to take myself off it because I couldn't deal with being 236 pounds. I had no withdrawal symptoms, and the weight started dropping like crazy. I'm almost 60 pounds lighter and sometimes struggle with eating 800 calories in a day. I wouldn't recommend going off it without permission though. My doctor was pretty pissed at me. I think he believes me now about it causing weight gain and hunger lol.
