Are you kidding me! Buck fever is the greatest feeling in the world. The secret is to practice shooting to the point it does not affect your shot.

correction the longer you hold it the MORE shakey you'll be

Agree with above. Once you know it's a shooter, worry about shooting, not showing the rack to your buddies, not how good it'll feel to have venison in the freezer. You know how to shoot, you know where to shoot, just don't "over concentrate" and you'll come through. I once followed a buck through my scope as he walked into an opening for probably 40+ yards...all along psyching myself out with "what ifs" and "is this the best shot?" But once I blinked, looked up, breathed, I came back to earth and it was natural.

WA Mthunter put it the best. Hunt a lot, or don't hunt at all. One of the things that will puzzle you is when it does not occur, then hunting become very special. One becomes very thoughtful, and hunting becomes very special.

I cant imagine not having buck fever, its the thrill of the hunt. I dont think you should try to aviod it, but instead just try to control it. And the following posts have offered the best advice to do that.

No one said not to get excited by the hunt. Just learn to control your emotions and steel up when it is time to take a life. It is just a game to many, unfortunately

I have avoided repeat hunts with silly, giddy, little ninnies that act like a little schoolgirl before during or after the moment of truth. All that nervous giggling and laughing is for the fools on TV.

use a solid rest and breath and squeeze the trigger, i try not to focus on the deer and instead on the spot your trying to hit

Bow hunt! Too easy, you usually watch bucks for a long time when and IF you get a shot at them. Also if you bow hunt the same place you gun hunt you will probably see the same bucks. Also try a trail cam, I find that if I get a good look at a good buck on the screen then I don't pay as much attention to the horns just settle on the cross hairs and squeeeeeze.
