"i can&#039;t say enough positive things about yaz. i was previously on tilia (estrostep) and recently switched. in only 3 weeks, my face has almost totally cleared up and my skin looks overall so much better. i seem to also have lost a little weight which is always a plus. the only one negative thing i can say is i am a little more tired in the mornings but it&#039;s not too bad. i would recommend this product a million times over."
