"i&#039;m 19 and have been on zarah for 2 years due to endometriosis. i don&#039;t notice my periods being much lighter while on it but that&#039;s probably due to my condition. i have had zero weight gain on this medication and my skin is always clear.  it made me a little nauseous i&#039;m the beginning, but nothing like what other bc pills did to me.  this is by far my favorite!"
