Nortriptyline
"I got a nasty flu virus when I was 32. During that time, I experienced my first migraine. It hurt so bad!  Afterwards..I kept getting them about once every one-two weeks. My doctor put me on nortriptyline. I have had one dose increase in the first year. Since then I don't them as much.  When I need to take it..it calms me and I fall asleep.  
The next day,I  get the migraine hang over..that's when I take ibuprofen. The medication has been a life saver"
