I take micrognon 30, combined oral contraceptive and I have yet to come across any bad side-effects.
I stopped taking them for about 5 months last year and noticed no difference in my skin, I've always had an oily T-zone!
The pill certainly hasn't lowered my sex-drive at all!
I know that it certainly increased my appetite a little, but I didn't gain weight as I noticed I was eating more and went to the gym 3 times instead of twice per week, after about a month or so my appetite seemed to settle back down and I have been fine ever since.
