"i&#039;m on yaz for 18 days now. i struggled with a sudden constant acne breakout on my chin (hormones). doctor prescribed yaz, especially to help with the acne. i am very happy with how the pill improved my skin. i&#039;ve noticed i can&#039;t drink the pill on a empty stomach (otherwise i am really nauseous). the only side effect i experience is the constant swelling of breasts. some days it&#039;s very sensitive other days not. yaz workers differently for every person."
