"i have been taking cryselle for 2 years now and i love it.  haven&#039;t had any side effects and the way it helps keep my period regular is awesome.  i know exactly when to expect it and how long it will last.  before cryselle i was taking another birth control that made me nauseous, gave me headaches, and would give me 2 periods a month. i love that i found cryselle and i will continue to use it."
