>>16725538 (OP)you've got a couple of options here
1- oxygen deprivation, followed by oxygen excess. used to do this on a submarine. was awake for a week once because of it.
2- ephedra spagyrics. this is the age old technique of extracting the active compounds from a substance with ethanol, water, and fire, then recombining all them into a freebased liquid form, like a tincture. ephedra, being the plant which bears the name for ephedrine, and you get the rest of it. its meth, but from a plant. the old timers used to use that on long marches, sea voyages, and battles. same as we do today, including that they knew you could drink the piss/cum of someone who had a lot in their system already for some recycling. sometimes they did that on purpose, like our gacked out tweakers do on their meth fuck binges.
3- modafinil and similar. do not recommend. I watched soldiers using this stuff to do week long missions, several times a month, for a few years. it'll kick the shit out of you even on easy days, not just hard physical labor and a high stress environment.
take it from me, friend, yer gunna wunna keep the sleep.
