lost a lot of weight with Topamax but their were several side effects, tingling and numbness, blood problems, bloody noses, confusion, left leg felt like I was having a deep vein blow up!!, THROMBOSIS???, even though I had all these problems I still wanted to go back on it because of the weight loss, I am crazy??, It helped my head aches so much too!!! some times my sweating would stop, be very careful on this drug, monitor yourself carefully!!!, this drug also controls your appetite.
