I don’t have CAH, but I can relate with a similar story of birth control pills.  I, like you, was a quiet, let it pass, no big deal kind of gal. Untill I started taking pills. Then it was all *** broke loose, what’s up her a**!! I knew I needed to get off them I like everone else at the time was starting to hate being around me. But I’m guessing you don’t have a choice? Sorry I can’t suggest anything. It really is the imbalance of the hormone levels. Maybe as time passes your body will learn how to control the Dex with your own hormones. Uhm... mean while try to run away when you feel rage coming on:) or  try my chill pill -BEER;)

GOOD luck.
