"i have been on a couple different types of birth control, and i have to say i like mononessa the least of all the ones i&#039;ve tried. i started taking mononessa about two years ago when i graduated from high school,  because my insurance no longer covers the birth control i was previously on. my senior year of high school i weighed approximately 125 pounds, and now i&#039;m up to 155. i can&#039;t say the weight gain is completely from the birth control, but i think it has mostly come from me switching. i am very moody, constantly hungry, and i feel as if i keep gaining weight. other than that, i&#039;ve been taking birth control since i was 13 (so for 8 years now), and i have never had any major problems."
