"i have been taking sprintec for about one month. i switched off of yaz which gave me intense mood swings, other than that i had no issues with yaz, but it was expensive as well. my obgyn put me on sprintec. i have missed a pill twice and had to double up the next night, both nights i was up getting violently ill, for 10 hours. i&#039;ve missed school because of this. i am going to wait 2 months and see if this stops, if not i will be switching. if i get an yeast infection this month i will not continue another month that&#039;s for sure."
