migraine prevention
"Well I was on Topamax for approximately 6mos.  My doctor hoped that he would be able to get me to the medicinal dosage of about 25mg twice daily.  However I could not stand the way the medicine made me fall asleep.  If I took it at 8pm, I passed out by 8:15. I can say that I was getting the BEST sleep of my life. I was afraid to take it in the morning before/during or after work, so I only took it once I got home. I only got to the 5mg dosage before I stopped taking it."
