"i started using yaz about a year ago - it has a good side and a bad side. good: less severe cramps, lighter periods, lighter facial hair (my little peach fuzz mustache disappeared). bad: emotional mood swings every month on the first day taking the placebo pill, dramatically decreased sex drive. overall i liked it and if i was not in a physical relationship then it would be great! but the decreased sex drive put a strain on my relationship so i am trying something different now."
