Terrible This is the first thing my doctor has given me for my migrains and it was awful. After taking, my headache didn't get any better and I thought I was dying. I experienced very strange side effects, including not being able to move (at all), open my eyes or talk. My muscles ached so bad and I became so naseaus that the migrain was the last thing on my mind (no pun intended). I find excedrin migrain works far better without the horrifying side effects, if im able to keep it down.
