ive been on aviane for about 8 months after switching from yaz because it made me SUPER emotional (crying everyday for no reason) and previously ortho tricyclin (made me feel flu-like symptoms the week before my period). the first month on aviane wasn't great, i was spotting and had cramps every time i took the pill. i decided to wait it out because it typically takes your body about 3 months to adjust to a new birth control. im glad i waited because i have no complaints now other than a loss of appetite. i lost close to 15 lbs (which is not necessarily good for me bc im 5'8 and now only weigh 110 lbs) and i went down a cup size (i miss my full C that yaz gave me hah). otherwise, my sex drive has increased drastically. before i barely even touched my boyfriend, poor him..but now i cant keep my hands off him. i don't really PMS too bad, so thats good too. i have some joint pains but i don't think it has anything to do with aviane.. all in all i say try it and just wait it out, the first few months may not go smoothly, but its not likely to with any new BC you try. give it a shot
