I found that Prozac made it so I couldn't feel, and like I wasn't myself. It also caused me to have severe nightmares, even months after my doc had taken me off of it. I also gained a lot of weight and had many other side effects. I've been through all kinds of antidepressants... the most recent was Effexor, but I decided to get off of it because I was sick of being emotionless and having those little bodily jerks all the time. My emotions are a rollercoaster now, and I'm not sure if I should be on it or not, but it's nice to at least stop gaining weight, and feel like a human being again.
