I never thought about using 5-hour energy drink for the BOB. I do use it though. Mostly for when I am driving long distances/periods; there is only so much music, gas stops, snack food one can use to keep one awake and alert. The 5-hour stuff doesn't crash me like straight caffeine does and is more subtle.

I supposed the inclusion would be based on what are your goals that you have in mind for your BOB. For example one of mine would be to bug out in case of a train derailment nearby. What do I need to carry so that I can get to a safe location until the clean-up or the OK signal from the authorities? I can't think of a reason that I would need 5-hour energy drinks in that scenario.
