I was on Yaz for 6 months and it was horrible. While I adjusted to the pill just fine after being on the pill for 4.5 months I started experiencing horrible mood swings, semi-depression, no patience, a high level of anxiety, loss of appetite, weight loss, gastroenterology issues, temper, feeling like I had no control, sleeping problems, over-heating, chills, etc. I've been off the pill for 3 months now and am just now starting to feel back to my normal self which is a happy, upbeat, motivated person. That pill completely changed my personality and caused my boyfriend and I to break up...the pill is the enemy, stay away if you don't want to be a crazy person!
