I get the same thing in regards with my med citalopram. Have you had eating disorders in the past? I was anorexic and i read the side effects of my med and it says it can cause anorexia, meaning i will have the anorexic thoughts again. I'm not sure if my med is making my gain weight, but i certainly feel very fat. take a look at the side effects, and then speak to your doc. i am changing meds for this reason.
