I was on that too for chronic headaches, migraines. My Doctor took me off of it. Not that I was abusing it, but he didnt want me on it for a long period of time. He then gave me toradol and midrim. Which also seem to work very good if I catch it in time. My neurologist gave me elavil for my daily headaches and that worked good for those. I have heard of alot of people having problems with esgic. Its the barbituate in it that I believe has the potential for addiction. Its hard to get off of too. My Dr told me to take 4 liquid advil caps at the first sign of a migraine and I can say that has worked great too. I havent even had to take any of my migraine pills in a long time. Good luck with this as I know how bad migraines are. Kim
