Yeah it sucks to be nervous for a long time. I was at first but then it settled down to just being nervous right before the session and then just nervous when I got to the waiting room right beforehand. It took a little time though, but not all that long. Try to distract yourself! Sometimes I was less nervous because I was so dang busy at work. (Guess it's obvious I'm not too busy at work today!)

Best of luck,
Sid
