birth control
"I used Yaz for one week increments for fertility treatments and was fine.  Then I decided to go on it for good(30's).  I was on it for two weeks.  I stopped taking the medicine because it made me crazy.  I said very hurtful things and actions.  I think if I continued I might have ended up in jail.  My poor husband.  I have never been abusive to anyone like that.  I still feel guilty."
