I have been on Diane35 for about 4.5-5 years now. It worked wonders for my cystic acne (and I mean 100% clear) for about 3 years, but last year, I started getting cysts and breakouts again. So my derm suggested Accutane, but I decided not to at that point. I went back on Minocycline and I am starting to break out again even with the Diane and the Mino, so back I go again.
I didn't have any breast size changes, or any real menstruation changes either. I think it took a few months before I noticed an improvement, so hang in there. However, I have heard on this board that Diane causes bad breakouts when you try and get off it, so you may want to discuss this with your Dr. I am facing that now, but I will speak to my derm about it.
That's all I need, you take something to help you but then you don't know how to get off it.
