Ask YC: We have a common challenge; share strategies to overcome it?

Stamina. Or rather the fatigue that results from lack of it. Ok, so while pursuing my startup effort, I've noticed a desire growing inside of me - a desire to locate some sort of establishment that caters to people like me who need meth-laced quadruple expressos. I haven't found such a thing yet, Starbucks refuses to even consider the need seriously - let alone research the market viability (I can't be the only one, right? - and my doctor doesn't believe my claims at being depressed and needing anti-depresents to "perk things up a bit" ... in the meantime - anyone want to share stamina hacks? I guess we can discuss workflow hacks to to figure out how to schedule things more efficiently so as to work more productively when starting a startup, but I'm talking about when you've woken up at 3:30am, and now it's 1am the next day, your brain shut off hours ago, and you don't want to eat for extra energy because you fear the blood necessary to digest the meal will hamper what little ability to think you have left as Adult Swim comes to an end. What do you guys use as "emergency" stuff? Meditation? Yoga? Ninja hand seals? stretching? Ice cold shower? Cross-brain stimulation drills? Go for a quick sprint outside naked? Seriously any new ideas I haven't tried would help just from a novelty perspective. Care to share?
