My pharmacist also switched to Aviane and told me that is was the same thing. I think that it has affected my bowels as now I have cramps there too. I feel crappy all the time. I also suffer from nausea in the morning and have thought that I was pregnant. I was on Alesse before that with no problems. I stopped taking the Aviane and asked specifically for the Alesse. Now my body is in some kind of limbo and I feel really low. I thought it was just me but I am "happy" to hear that it is not in my head. I think I will come off all BC for a month or two and try again,
