I still go through it - it's "buck" fever, which for me is simply deer fever. I get so shook up at the shot that I really have to fight to focus on my spot and execute. This happened pre-traditional too. That major adrenaline rush is something I cherish and one of the primary reasons I love to hunt. If it goes away and I ever become unaffected by the shot - I'll no longer hunt.
Keep after it, and just talk yourself through your shot each time. ..."focus on a spot, aim low, smooth release, focus..." You get the idea.
I will say that I have stopped "grunting" to stop an animal now that I've gone 100% trad only. Our bows are too slow to shoot at an alert animal - period. I'd rather shoot at one walking than grunt at him/her to stop only to watch them duck the arrow.
Good luck and keep your head up!!!!
