"i was taking sprintec and never had any issue there. then i moved and the new pharmacy gave me this generic one. i thought they would be the same and i was completely wrong. i took them for three nights just to get my body used to the change. each night the pain got worse and worse. i was waking up at 2am with terrible abdominal pains and i could not stop throwing up. i stopped taking them yesterday and today my stomach is feeling a little better. i am now going to get back on sprintec."
