One of my first pdocs said that every drug can affect everybody differently. Everyone has a different metabolism, a different blood chemistry, etc. Some drugs that make some people gain weight don't affect others that way.

I have body dysmorphic disorder as well as BP II. I personally think I would not be able to stay on meds that caused me to gain a lot of weight. That is very sad to me that I would rather be out of mind and miserable, than overweight.

Being mentally ill doesn't make sense.....
