I take it for regulation and emotional purposes also and I LOVE IT! It hasn't totally brought back the sex drive that the Mircette made me lose but it has regulated me, I too love knowing what day I will start (and it's generally to the minute also) - the cramping is 1/4 of what it use to be (I still get cramping), the bleeding is lowered also. I still have some PMS symptoms but I don't get the headaches I use to get and I don't get the bloating I use to get (it use to be BAD). I also am not an emotional wreck either - I was on antidepressants at one point because I needed the pill for regulation but it was whacking out my emotional state. Went off of those immediately. When I was on Mircette I also had horrible water retention and I have very little (I still have some) with Yasmin. I really do love this pill.
It does lower your sex drive some though but for me I think some of that is also still emotional too.
