I just had 3 red bulls and im raring to go.
Dont worry, i stayed up all night for trials and i got 93 somehow.
Think of it this way, get a cold shower, drink some V or red bull and ull be wide awake.
If you sleep now, ull have little amounts of sleep and ull be tired when you wake up. And believe me, your mind is clearer if u stayed up all night then waking up in the morning feeling like shit.
