DISCLAIMER- This is NOT meant to make you feel your best, it is a technique I use to make sure I get enough sleep the night before a contest. I also use this technique to make sure I am not falling asleep at a contest or demo.
I don't have many precontest tricks to tell other than the supplements I take,
the training I put in, and the rest I take prior to a contest. HOWEVER I do
have one technique I use that I have not heard many people use, sleep cycling.
It is very basic and really does not require much planning (and no supplies!).
THIS IS MOST EFFECTIVE FOR GUYS (or gals ;) ) THAT CAN NOT SLEEP OR ARE
RESTLESS THE NIGHT BEFORE A CONTEST.
For this example I will say the contest is Saturday morning at about 10am.
Thursday night I will fall asleep the normal time I typically do, HOWEVER I
will wake up friday morning at about 6am, maybe 5am (needs to be ~2hrs earlier
than you are used to) now this will make you feel kind of crappy most of day
but so long as you do not get too excited about anything you will be ready for
bed by dark/7-8pm. Fall asleep early Friday night, wake up at 7-8am Saturday (8-12hrs
sleep) and kick some ass in the contest!
