obesity
"I am stopping Topamax after 3 months.  Initially I lost 13lb pretty fast, within a couple weeks.  I was laid up with an injured back and sick so I wasn't moving, but then I wasn't really eating either.  Since then I've played with the same 5ib.  I am taking 100mg 2x day.  After about 6wks I got some of the common side effects (vision, memory, taste, exhaustion), I stopped losing weight.  But I'm fairly certain it is the source of some pretty severe depression that didn't exist prior to taking it.  I'm glad I lost 13lb, but the depression is too much to handle and I'm throwing in the towel.  Wish it had been more effective, but really it stopped working after about 3 weeks anyhow."
