I was on Diane for about 5 years - when I came off I felt so much better!
More energy and less moodiness! Also I used to get PMT quite badly whilst on pill - sore bb's, bloating, cramps and headaches. Don't get any of that anymore except for the occasional headache.

Pimples came back but not as bad as they used to be

Improved libido

AF is heavier now but not longer

Can't comment on the weight as pill didn't make me put any on
