"the triphasal birth-control pills have been a lifesaver for me to help control my bipolar disorder for over 20 years   off them, i have horrible mood swings and other symptoms like insomnia around ovulation and before my period.  are used to take tri-levelin until they discontinued the brand name version.  my gynecologist put me on this and within a few days i noticed a big difference.  with the extra progesterone,  i don&#039;t get such horrible highs and lows like a roller coaster."
