I am 38 and took YAZ for two years. At first it seemed like a wonder drug. I didn't have a period the entire time I took them and my MD said that was normal for some women. After about a year, I started having night sweats, leg cramps, and increased moodiness...like things that should just aggravate me made me down right angry. I also started having considerable swelling in my hands and feet that was present most of the time. After a night of research on the internet trying to figure out what was wrong with me (my thyroid?) I landed on a few sights about YAZ and felt like my prayers were answered. Every single thing that was happening to me: sweats, swelling, cramps, low sex drive, fatigue, headaches, GI upset...could be attributed to YAZ. I stopped taking it immediately. It's only been about a month and I'm still feeling a little tired and moody, but my legs don't cramp, my rings fit my fingers, no more night sweats, and I have the hots for my hubby again. Life if Good! :)
