Yes Dave. Often drive with windows down, arms out to make them cold then rub over my face.
I would say not eating. Works for me. I am always ill or tired and eating makes me worse. Candy crush or a game on your iphone, keep your brain active while playing the earlier levels. I also find leaving min way through the levels to have 5 mins outside helps, insted of literally sitting there till the breaks. Make banter aswell, random prop bets and such. Keeps u focused on othet areas when your not in a hand or you need to watch a hand play out. Drink coke not red bull.. The crash on that when tired is ridic. Good luck mate. Play ABC and let everyone else make mistakes.
I always wondered what it was like for the undead!
I just tend to go heavy on the coffee.
