To me, there is a big difference between getting excited at seeing a deer and buck fever. With one, you feel the excitement and can adjust, the other is that situation where you cannot calm yourself enough to gain control of what's at hand. The main objective at that time is to make an accurate shot at the animal and we all know it can be easier said than done. There are a few things that may help, that I have used over the years. First of all, expect to see deer when you're hunitng and play over in your mind what you'll do when you finally see him. Be prepared for the unexpected (which can happen quite often) and how you will react. What if he comes from the side? What if appears from behind me? Play these situations over and over in your head during the course of the day, so you can be better prepared when the time comes. The other thing that I have found helpful, is "Now what do I do"....when I have found myself face to face with that buck. Don't be afraid to talk to yourself, tell yourself, "OK, let's be cool here, take a few deep breaths and try to settle down. To, me, being patient is the key here....if you decide to rush things because of your anxiety, you will give that deer the one thing that he needs to survive....that is he reacts before you. The big picture here is to see and know the deer is there before he knows you're there. So you can get prepared to take an accurate shot. Buck fever happens to almost everyone, there is no shame in it unless you let it continue and affect your success as a hunter. Anticipate where you expect to see deer, decide what you'll do if all of a sudden he materalizes within range and tell yourself you must take the necesary steps to try to avoid getting buck fever. This will take time and practice, but having a game plan if/when it happens is a lot bette than being at the mercy of the fever.
