Pre-Match supplements and nutrition

[TxRugby_8]

I'm always looking for an edge on the field and was wondering if anybody knew of any good secrets to boost performance prior to games/matches. I play rugby at a very high level, so every bit of endurance counts.
This is my current day of match (afternoon kickoff):

wakeup - 1 c oats and 2 scoops of whey protein, multi vitamin
2 hours later - 1.5 c oats, 2 eggs, 6 whites, veggies
30 min. later (2 hours from kick off) - my "endurance" cocktail: creatine, ribose, potassium, malodextine, dextrose, and protein.
30 min. before kickoff - 1 large orange if i don't have butterflies, 1 adderall

i also drink about 3/4 a gallon of water in this time

if you have any ideas let me know.

cheers
