I am a 25 year old woman with 3 kids. I was prescribed TOPAMAX 3 months ago. I am on 150mg a day. My DR. told me to take them at night before bed and I have to take a TYLENOL PM with it so I can sleep at night and drink 64 oz of water a day and 8 oz of citus a day to help flush out my kidney's, cause TOPAMAX does cause kidney stones. I was having about 17-20 migraines a month before getting on this medicine. They have cut down to about 5 but I take RELPAX and in about 30min my migraine is gone. People who don't know I am taking the TOPAMAX don't notice my side effects. I do have some side effects, memory loss, loss of concentration, I have lost about 15lbs with the help of dieting I was 134 now at 118, spelling, sometimes my words come out abit slured, my eyes are sensitive to light I need sunglasses to go outside,.I feel tired sometimes no matter how much sleep I get. Well I hope this helps...
