"i have been on aviane for about a year now and by far the worst side effect of it is the weight gain and breast tenderness. i haven&#039;t experienced any other negative side effects. i&#039;ve gained 20 pounds in the last year, i feel frequently hungry, and more recently, bloated all the time. i&#039;ve gained an entire cup size which under any other circumstances would perhaps be nice but i already had larger breasts for my small frame and now they&#039;re just out of control. to go from 5&#039;4 with large cs to gaining 20lbs and large ds is just really very uncomfortable. i have unsuccessfully tried to lose the weight but i have now decided to change my birth control entirely."
