birth control
"I was prescribed this for birth control because I didn't like the weight I gained on Yaz, but it was a mistake. For weeks I had horrible headaches to the point where I couldn't think, and then had terrible mood swings. Effective as a contraceptive, because I didn't get pregnant, but I was confused as to why I didn't feel like myself at all. After I figured out that it was probably Kariva, I stopped immediately.  I had no clue birth control pills could make me that crazy! After a month, I felt much better. Not taking this ever again."
