"not terrible, but not great. i&#039;ve only been on it for one month so far, but i&#039;ve been constipated, bloated, and my eyes have been bugging me/ i got nauseous for the first two weeks of use, to the point that i had to take prescription medication for nausea. there&#039;s no difference in my skin (still pretty clear), and i get headaches periodically. i&#039;ve also had trouble concentrating. this did nothing for cramps either. i didn&#039;t get pregnant, so i guess it&#039;s doing it&#039;s job, but i&#039;ll probably switch to another brand."
