Diabetes: Topomax for weight loss?

I typically lurk on this list--on most e-mail lists, actually, because I try to read too many of them. My doctor suggested that I consider trying Topomax to help with weight loss. She said "Do some research, and see what you think." I'm not thrilled with some of the potential side effects, but overall, I've had a good history of tolerating a variety of medications without any obvious side effects. (The only thing that's ever given me problems was Avandia: I had daily, intense headaches on it.) Since weight loss is a side effect of Topomax, and I usually don't experience many side effects, I'm wondering if it's worth trying. Has anyone else taken Topomax specifically for weight loss? If so, what sort of results--if any--did you have?
