The accounts I read vary in usage from 100mg 3x/day to 800mg 2x/day, with results from very bad to hugely successful in diminishing migraines. How does a person figure out if this is the right remedy for them, and then the dosage level?? I have midnight migraines, which have been diagnosed as resulting from grinding (I've worn a mouth-guard for the last year), and when I wake up with one I take a Fioricet, drink half a Coke, then sit up-right for 45 minutes to 2 hours before I eventually fall asleep. I wake (normally) feeling refreshed and good. Am I a candidate for gabapentin??
