"my doctor suggested kariva to me because i was previously on ortho tri-cyclen (which made me extremely moody/emotional) and more recently lo-estrin (which gave me no sex drive whatsoever and made me completely emotionless).  i was anxious to find a happy medium after going from one extreme to the other.  i&#039;ve been on kariva for three months now.  i&#039;ve never been one to have any type of headaches of any kind, and after being on kariva i experience headaches multiple times a day.  i&#039;m extremely tired all the time and i&#039;ve gained weight in my breasts (i&#039;m naturally a d and i&#039;ve went up to a large dd). no sex drive, extreme mood swings, acne and increased appetite. i can&#039;t wait to get off this pill.  look for other options before taking kariva."
