I gradually allow the anticipation to build until at about a half hour before kick-off I'm at the level of "pre-game jitters". After a few minutes of the game I'm usually getting pretty well calmed down and into the jumping up and down and cheering and high-fiving and just plumb enjoying the game.
The anticipation process will start to increase around 8 AM tomorrow. It slowly (hopefully) builds until at about three hours before kickoff I am at a point where I begin the physical relaxation exercises. I jump up and down and shake my hands and arms and take deep slow breaths just to keep the anticipation from increasing too rapidly. I keep my level of caffeine and sugar intake down so as to not get over-hyped. I never drink alcohol before a game as that would interfere with the whole anticipation-building process.
If I've managed the anticipation process and the participation as a fan well, then by the fourth quarter I'll be so wrung out that I will feel as though I've actually played the game. After the game I will have a deep calm physical, emotional and mental feeling in that I did my best and laid it all out in the stands. Maybe then I'll get a cold beer and slowly drink it, enjoying every last drop and feeling very satisfied with our win.
Basically it's been the same procedure for every Cyclone game for the last forty years (except for the no alcohol before the game bit, I added that to the procedure as I got older) and every game is total excitement and anticipation for a good game and hopefully a win. Go Cyclones!
