"i have been taking previfem for about three years now. the beginning of each new pack i get extremely sick to the point of puking all night &amp; can&#039;t keep anything down. on the bright side, i&#039;ve had a lot of unprotected sex &amp; i haven&#039;t gotten pregnant so it does work for birth control.

time to switch. can&#039;t handle the up all night sickness anymore."
