"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&#039;m lucky if i&#039;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."
