"From the first month until 6 month that I took the pills I have experienced the worst migraine ever.  The migraines were so horrible it make me throw up every time. These migraines will last up to three days if I'm lucky if I'm not lucky it will last up to a whole week. It took my four months to realize it was the pills because I was so sick from the pills I stop taking it for a week. After that my migraine went away and came back right away after taking it.  I just stop taking the pills after that and switched over. However ever since taking the sprintec I will occasionally get the same sickening migraine but it will be one day of the month now.  It has been six months since and I am still having migraines due to taking the sprintec."
