I want to say thanks to everyone for posting so much useful information. One thing I can say is that I'm glad I have a doctor who really listens to me and makes time for me even if he doesn't really have the time. The last one I had was part of the problem - he tut-tutted everything I ever said then did what he thought was best..which is why I had no medication and no diagnosis for years. Of course, I was too intimidated to speak up or to change doctors...I can do that now.
