Acetaminophen / butalbital
"I've been using Phrenilin for 25  years.  I was in an accident 30 years ago and suffered with migraine.  This medication is a life saver.  I would certainly tell anyone to try it.  Cheap enough ($7.29 for 20 pills) and quite often I will cut the pills in half depending on the strength of the migraine.  I take at the first sign of migraine (unless I wake up with one, of course) and probably another one after that, and the migraine is at the very least under control.  Would absolutely suggest."
