TOPAMAX - Weight Loss

I’m currently taking Topamax to help with weight loss. I started three weeks ago at 25mg, and I’m now up to 75mg. Since the beginning, I’ve been feeling really sick—stomach pains, gas, nausea, extreme dry mouth, and constant thirst, even just for water. I’m also experiencing frequent urination that I can barely control. My mind feels anxious from all these uncomfortable symptoms. I’m speaking with my doctor tomorrow, but I’m considering stopping the medication ASAP. I came across a few forums where people mentioned having strokes as a result, which is really scary. Has anyone had a positive experience with Topamax for weight loss?
