Hello there! I used Diane 35 for about 6 months and I had some pretty crazy mood swings and some beautiful new course black hairs on my cheek to add to the lovely colection of pimples that never really seemed to clear up! On the other hand my friend is still taking it and loves it her face has never been clearer! She does however have to way that against the fact that she developed the same nasty little black hairs.
