"i changed to yaz after my other contraceptive (levlin) made my skin breakout and made me irrationally emotional. my skin cleared up in 1 month! i didn&#039;t have cystic acne but i always got big patchy breakouts. my skin is so smooth and i&#039;m a lot less emotional lol. i&#039;m also on a whole bunch of medications for epilepsy so the fact that this pill can level my emotions is pretty fantastic. i haven&#039;t experience any muscle pain, acne worsening, or any other of the side effects other people have mentioned. guess it depends on the person. i&#039;ve also noticed it has given me more energy which means i can excerise 5 times a week instead of 3 which is also much healthier for me! definately give yaz a try!"
