"the first three weeks on cryselle were pretty awful. i had headaches and stomach pain constantly. but after the first three weeks, all of that ended &amp; now i take it without any issues. as long as you get through those three weeks &amp; stick it out it&#039;s awesome! i&#039;ve lost weight, my periods are light and short &amp; my acne is gone. definitely recommend this! just push through those first three weeks!"
