Making instant coffee over an open flame, in public places, is becoming easier. I mix three large spoonfuls of instant garbage into a cup of water and stir. This makes it taste even more terrible, but it's the only way I can actually feel the caffeine.
I ignite enough alcohol in my stove so it heats up the liquid to just under boiling before going out. I use clean drinking or tap water for this so it's unnecessary to bring it to a full boil.
Dollar stores are abundant up here and they're seriously saving my ass. Last night I bought a 2QT, wide-mouth, plastic container and filled it up with duplex creme cookies. Now I have a cookie jar and it only costs $1-2 to fill it up.
I'm all about those small victories in life.
