Topamax and vengeance

I've been on Topamax for 3 years for migraine and it works most of the time. I am currently having a hard time with the usual side effects of memory loss, hair loss, word recall problems, coldness, depression, no sex drive, and am developing a cough. BUT I had a side effect that has not been mentioned when I first started taking it (25 mg in am and pm -- I'm now on 50mg in am and pm).
For about 2 weeks, I would get in my car to go to work and miss my turns because they would cognitively come up too soon (this is after 15 years of going to work the same way everyday). I had to be extremely conscious of my surroundings when I drove or I'd miss all my normal turns. I got lost in my own neighborhood once going home. At work, I'd get up from my desk to go to a co-worker's desk and arrive there amazing fast to my mind. I was experiencing time/space/distance distortion. It became fascinating to me, but it passed.
