depression
"I started this after talking to my doctor about how I was scared to gain weight with an antidepressant (I gained 15 pounds on Zoloft). 
This medicine made me feel crazy! I took it for 2 weeks, and every day I felt like there was a brick on my eyes/head. I felt like I was going to have a seizure any moment (no I've never had one, I just felt like I was going to). I was sensitive to light, and couldn't see when I was driving at night. It was awful!!! I'm on Prozac now and seem to be doing ok :)"
