depression
"I have been taking this medicine since it's been out on the market, I remember my doctor telling me it was new and give it a try.  I felt like that is when all the cog works of my brain started working in conjunction with one another.  I could see life as it really was.  It actually gives me headaches, but after trying about 20 diff medicines, this works.  I take it with Topamax and Wellbutrin.  20 years on a medicine isn't bad."
