"I had slight decrease in Libido.  Nice light periods.  Cleared up my acne slightly - I have cystic acne.  No noticeable weight gain.  I do wear contacts, no trouble with those.  Overall I was happy with it.  Was on since I was 15/16 years old for about nine years straight.  Switching to Yaz to see if that helps better with my acne."
