Topamax and fog

I have been on Topamax for 2 months and it has been horrible. I started at 25mg at bedtime and worked up to 50mg at night and 25 in the morning. I wish I never took it at all. I have had numerous migraines with the medication except now my tongue goes numb every time. I can't remember anything and I am in a fog all the time. I had to take a trip to the emergency room for tachycardia that occurs every time I stand. It goes up from normal to 166bpm. The cardiologist insists the Topamax is causing orhtostatic hypotension. I stopped all of the Topamax on Monday and it is now Saturday and I still feel horrible. Migraines are horrible but being stuck on your couch all the time because your hr increases sharply and you feel like you are going to pass out is worse. My hands and feet tingle all the time. I feel out of breath and I have always been very active. I now feel anxious all the time (never like this before). I feel like I am not myself and I am going crazy. I do not trust myself because I do not feel like myself. Has anyone else had these symptoms? Do they eventually go away? The cardiologist can't guarantee that they will ever go away.

I began reading all of the blogs about Topamax and was surprised. I have been taking Topamax as a mood stabilizer since February 2007 at 200 mg at bed time (I probably sleep off the fatigue). The only side effect I am concerned about is the weight loss. Short term memory is not an issue. As a matter of fact, I am attend college and am managing a 3.85 gpa. I wish all of you the best of luck and hope you find something that works for you.

I began Topamax in August after 6 months of ongoing severe migraines. They stopped immediately. My DR had warned me of weight loss but I thought who cares? I weighed 130 at the time. I have had a fatigue problem for years so I really can't attribute that to Topamax. I did become very sick (exhaustion-couldn't get out of bed) after Christmas and had my DR take my ANA which was 1280 (high). I have also experienced hair loss but I did not find that on the "side effects". I called the hot line to see if there were other reports of affected the ANA count and they had no data on this. Has anyone else had this experience? Meanwhile, it is 8 months later, I am down to 96 lbs and worried, have lost all fat & muscle - no migraines!
