migraine
"I've had migraines for the last 10 years.  Replax is the 2nd prescription I've tried.  Two hours after the 1st dose my migraine was no longer in the usual cluster location my entire brain was ready to explode.  As directed I took the 2nd dose.  After 8 hours I finally felt better in that I could function again.  24 hours later I'm still "foggy", sleepy and have had several rebound headaches.  I will not take this drug again."
