acne
"I switched to yaz from alesse because I heard it was better for acne. It did wonders for my skin and only having a 4 day period was nice too. However, I did notice that I was more emotional and had crazy mood swings, I found myself crying for no reason (not very good for my relationship either). I didn't gain any weight, and had no other side effects. I only switched back to alesse because my doctor expressed a concern about the blood clots possible with this birth control, otherwise I wouldn't have switched. Goodluck!!"
