"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't be able to tell a difference, but for some reason...I can.  What a nightmare."
