migraine
"This medication will help with my migraine headache for the day but I wake up and still have a terrible headache once the medication subsides.  I seem to get terrible rebound headaches and have to repeatedly take this medication hoping each day that I will be free of the migraine.  I am now on day number four.  I was told it was supposed to be better than imitrex because it would not cause rebound headaches but it doesn't work for me."
