I have Bipolar Disorder and was put on risperdal for 3 weeks. 3 weeks only! I had to be taken off of it. It was an amazing drug that really helped me with what I was going through, but it made me eat like crazy! It felt like I was a wild animal when food came around. I would smell someone elses food and be unable to resist the urge to eat soooo much or think about anything other than their plate. I got so embarrassed by the way I behaved when I was around food that I began to eat in private. They put me on ability now and I feel just as good as when I was on risperdal but now without the food problems.
