"i&#039;ve been on this birth control for almost a year. it started out great and my periods were regular and light. my breasts also got bigger, which was an advantage. right away i noticed the biggest change in my lifestyle: my sex drive plummeted and i became extremely emotional. i went from having sex with my boyfriend every day to maybe once a week, and it so difficult for me to get turned on. i&#039;ll watch a commercial with a dog in it and cry, or sob uncontrollably when my boyfriend does something nice for me. it&#039;s ridiculous. i also gained a lot of weight since starting mononessa, and always feel tired and foggy. it has been effective with preventing pregnancy, but is not the right birth control for me."
