Drospirenone / ethinyl estradiol
"I'm only on day 2 so my opinion might not be worth much.  But here's how I feel:  I take the pill at 9:30PM, its somehow preventing the Tylenol 3 I take for pain from working properly.  I feel really fresh in the morning, tired through the day and then ready to hit the bed at a normal time at night.  Overall so far, I like it.  I don't have PMDD or PCOS, my Doctor had me on Alesse because Tri Cyclen was causing me hives.  On the Alesse I realize I felt really anxious and didn't even consider it was the pill until I took Yaz.  Now I feel kind of relaxed and not concerned about everything being perfectly clean.  I'm also hoping for the weight loss and breast increase like others.  I'm 5"1 and just ballooned to 115lbs over summer BBQ's."
