"i had a terrible experience on this - i was on a similar generic pill, and my insurance/pharmacy sent this instead.  within days of being on it, i had headaches, nausea, mood swings.  i also have not been able to sleep through the night in the last few weeks.   i have thrown up about 6 times in the 3 weeks i started the pills and my boyfriend thinks i am insane from all the mood swings.  i am switching back to the other generic pill-which i realize you shouldn&#039;t be able to tell a difference, but for some reason...i can.  what a nightmare."
