"i have been on yaz since june of this year and at first it was okay but no i can&#039;t stand it. i&#039;m always tired and i&#039;m not in the mood to do anything. i&#039;m 18 and just started college and met a guy who i&#039;m crazy about but the bad thing is he has to put up with me being tired and moody all the time. another thing about being on yaz is that i never know when i&#039;m going to get my period and even between periods i have quite a bit of bleeding. i called my doctor today and she said she would call in a new prescription for me to try so lets hope it helps! i wasn&#039;t sure if it was stress about from my college courses that were causing me trouble but then i started reading other people experiences on yaz and they have been going through the same thing."
