Here I am again, with more questions about topamax...I upped my dose to 50 mg. and got so sleepy I couldn't function! Did anyone else do that? I mean I just couldn't stay awake. How does anyone take 100 mg? I had to go back to 25 mg. just to be able to get out of bed in the morning. After taking it about four days, I was so sleepy I literally couldn't move. Tibbie, help!
