"i started using yaz 3 months ago. yes, it has helped my horrific acne but along with that comes other side effects. my breasts have gotten larger and i have lost weight (gained from quitting smoking). but i&#039;m extremely tired in the morning, nauseated, feel like vomiting, headaches that turn into migraines, and lack of sex drive. i&#039;m waiting til the end of this cycle to decide which side of the fence i want to be."
