What you need is ...
A large cup of coffee, mix in one teaspoon of crushed garlic and a large dollop of hot sauce.
Stir that and think to yourself ... am I really tired enough to drink this? If you can't think of a reason not to, down the hatch.
Chances are, your neurons will simply act in self defense and you will get a surge of energy.
Hahahaha,I actually love chilli concoctions but that certainly would be boufing! I don't think I would ever convince myself I was tired enough!!
