I think everyone has different reactions to different forms of birth control. I was on Alesse for 2 years with zero problems. Then one day my pharmacist offered me the generic form Aviane and told me it was the same. I decided to get it since its cheaper, but now I wish I hadn't. I had some of the same symptoms listed here on Aviane, like yeast infections, low sex drive and thinning hair. So I'm going back to Alesse which was always great for me. Everyone needs to listen to their bodies and make the best decision for themselves. Good luck!!!!!
