I just came across this site while I was researching Yaz..and just had to write a post!... even though birth control pills have a different effect on everyone.. I have to say I LOVE Yaz. Ive been suffering from severe acne since I was in 8th grade and have used almost every product out there. I would wake up sometimes 40 minutes before school and work ect to put makeup on and would be so frustrated! I was worried about having to do that now that im off to college with a floor of girls but i dont! Ive now been on Yaz for 3 months and not only lost 10 lbs but my skin is flawless!! Ive been on proactive, clean and clear, acne pills from the doctor.. and nothing has been better than this!... the only side effect if anything is that I too am also very tired sometimes..and my first month of taking pills I had a day or two of breakthrough bleeding...but otherwise that its perfect. I was originally on ortho tricyclen lo and it made me unbelievably moody and depressed. But I dont have that problem at all now... very happy go lucky.. but maybe thats because I finally have great skin! I would definetly recommend this to everyone... even just to try... what do u have to lose except the acne!! I have to say I was very unsure when I read that 9 out of 10 women show moderate signs of improvement with their acne while taking Yaz...but it definetly worked for me!
