birth control
"I started out on Yasmin but had to switch to Ocella since I have no prescription coverage.  Between the two I was on them for over 2 years.  In that time, I gained 20 pounds.  After I switched to Ocella,  While I was taking it, my moods were level but the first day without the pill I felt completely out of control of my emotions and on an emotional roller-coaster to the point of having to leave work a few times, which is not me at all!  Once I got my period, it was better but I didn't look forward to the next month.  After a crazy month of break-through bleeding, emotional ups and downs, and feeling like I was going crazy, I asked my doctor to switch me to something else.  My sister had the same symptoms within a month or two and so did friends."
