I took YAZ for 9 months. Within those 9 months I have noticed that my mood was completely different from my mood when I was on Loestro 24. By the end of 9 months I was depressed, worried about everything (especially right before my period) crying all the time, and down right crazy! I don't have PMDD, and I don't think it is good to take this pill unless you know that you have it. This pill emotionally made me crazy and caused me a lot of depression which is something that I am not used to. I switched back to Loestro24.. and felt 1000 times better the next month, my only issues with that pill is that after a long period of time of taking this pill, I get acne all over my legs, which is weird. I recently tried to switch to Femcon FE... and that was terrible, I was really sick from that pill. I don't know that birth control pills are the answer, they all have some kind of weird side effects, but I do know that I would not recommend YAZ to anyone who doesn't want to cry every month. This pill made me crazy!
