"i&#039;ve only been on this for a few days, and i know my body needs time to adjust, but i just spent the last 4hrs (3-7am!) throwing up without cease. i have had horrible, horrible cramps, like, on-the-floor-screaming cramps (which is why i started taking these pills), but at least those only lasted an hour at a time tops! i&#039;m worried about missing school, and i can at least try to manage my cramps like i have before. i can&#039;t vouch for its effectiveness, only the side effects i suffered, but i may consider trying it again during a break when my body has time to adjust without worrying about missing classes."
