Well, I can't speak for you, but, I know I can get irritated and aggitated, and also anxious without sleep too. So, *I* wouldn't touch a Red Bull or any of those types of drinks, myself.
Seems to me the music itself would give you the energy to keep you going, no?
And, as far as keeping up with the others, well, if they are drinking and smoking, you'll be far ahead of them by keeping your head straight! They are the ones who will be nodding! :rof
Just my opinion. Take what you need and leave the rest, as they say...
Shalom!
