I been taking 100mg 2xday Topamax for about 8 mths now. My psychiologist doesn't give me but 5 min tops with him and I refuse to see him again. After doing research on my own, I found it Topamax interacts with almost half of my medications, that's why I am stopping it. Plus I can't deal with the side effects anymore, the only plus side is it has helped me lose some wgt. My question is: how long before it is out of my system?
