"i have been on cryselle for a year and 1 month and i love it. i used to get the worst acne on my chin but my face cleared up for the most part while on cryselle.the first 1-2 weeks on it i was kind of nauseated and threw up once on the first week. i was irritable a bit the first 2 weeks. and my first period on it was painful. i started cryselle because i had unpredictable painful periods  &amp; it really has worked my periods are light and only last 3-4 days. almost no cramping, sometimes none. plus i know when i&#039;m getting my period and i&#039;m able to make sure i am not on my period on important an important events. plus it has protected me from getting pregnant ever since i became sexually active. first month is tough, after that it&#039;s amazing!"
