Started on Topamax about 3 months ago. Taking for visual seizures from scar tissue due to gamma knife on an AVM that bled.I was seeing all kinds of things like people, dogs, cars, you name it. Doctor first put me on Dilantin (pretty strong dose). It did nothing, and it did not even show up in my blood on a blood test. That was a nuerosurgeon. He sent me to a nuerologist. He put me on lamictal. I took it for one week, and wanted to drive my car over a cliff!!! I was so depressed and I felt horrible. I just stopped taking it. Then he put me on Topamax. I take 100mg. Soda is bad. I do miss my diet pepsi. I lost 30 pounds ( this is a benefit). My brain is fuzzy at times, and I can go to introduce a family member, and not even remember their name for a minute. I have trouble with urination, actually starting it. Sometimes I lose my balance, and bang into things. I get stomach cramps once in a while.However, all the people, dogs, cars, and "unwanted" visions are gone. So, I guess it is worth it. I wonder if I will ever like Diet Pepsi again. Also, now eggs and chicken are really starting to gross me out.
