does Topamax cause weight gain or nightmares?

I think I have read that it can cause nightmares for some people. It often causes weightloss, but everyone is different. Some have the opposite affect. From what I understand, the weightloss is from loss of apetite since it affects how things taste....

It cut my appetite, so I have lost 15 lbs. in about 2 months. Also I had some funny dreams maybe just the first week I was on it but none other than that.
