"i&#039;ve been on it for 3 years with 0 side effects. it&#039;s effective in that i&#039;ve never become pregnant. i haven&#039;t experienced mood swings like everyone else posted about. i never get breakouts. the only reason i&#039;ve gained 10 lbs in the last 3 years is from crossfit and it was muscle. i have absolutely no complaints with estarylla."
