I started taking the pill a month and a half ago. Started out with nausea for several days, but the severity lessened with time. After I started taking my second pack, I started having really bad mood swings, decreased sex drive, bad cramping, depression and nightmares. Before taking this pill, I was emotionally stable and had a LARGE sex drive. I found myself being very irratable and vicious towards my boyfriend. I thought taking birth control would help me have less painful periods, but I think I would rather deal with that than being a bitch all the time!
