"i been on mononessa for the past 2 years and have only stuck with it this long because it was the best i had yet to try (was extremely sick on aviane and had heavy, long, unbearable periods with ortho tri-cyclen) and it was free on my insurance. after 2 years my periods are still irregular, i experience recurring  headaches, and i&#039;m constantly bloated and have gained 10 pounds. not to mention moodiness, feeling foggy, and decreased libido.
