I just quit YAZ. I too thought it was great at first. Raved about it. Not sure if it was working or if just the promise of the potential benefits that made me think that. I have a history of Lupus symptoms that I am only now tying together. I was feeling SO BAD that I started researching lupus and found that it can exasperate the symptoms. i was having heart palpitations lasting for nearly 20 minutes, shortness of breath doing small tasks, inability to take a deep breath, NON EXISTENT sex drive, SEVERE depression, and the last straw was the constipation/diarrhea cycle. i too had slurred, stuttered speach...but did not correlate the two until reading comments. my motor skills seemed to be effected. doing what i absolutely needed to do in a day was all i could manage. this may be a combination of factors coming into play, but there IS NO DOUBT that the timing of me starting this pill corresponded with the exasperation of these symptoms. i quit less than a month ago. hopefully things will improve. doctors need to take more precaution in perscribing this. my doctor was new to me and was quick to perscribe, no hesitation. i encourage you to insist on lots of tests before trying this. check your liver, kidney, potassium...be sure, then try at your own risk.
