I hate to say this but survival sometimes pushes you beyond what do you have in your pack that can keep you going 3+ day no sleep while doing excessive hard physically demanding things? Caffeine only so good sugar ok but where do you go when you have to go beyond?
In past they used drugs to keep troops going, this is not a good thing but may make difference when you absolutely must or die. you may want to look into ways to extend your capabilities should the need arise. It creates problems in other areas when solving the sleep issue and creates a debt that must be repaid but sometimes no choice.
rowan with the chickens hypnotize them first easy on them and you to kill them
