"i&#039;ve taken oral contraceptives for a couple of years, almost 10 years ago. i decided to try again and was prescribed orsythia. while it does its job - i&#039;m not pregnant -  i&#039;m constantly tired and sleepy, my sex drive is almost nonexistent now, my breasts often hurt, and the first day of my period is very painful. i can take tylenol for the menstrual pain but other side effects are unacceptable."
