what do you do?

Ground up some nutmeg nuts and eat it. That should occupy you for at least a day and a half. Except, you'll never, ever, ever, ever be able to eat nutmeg again without feeling sick, because that shit is vile.

What would be better is to just ... not smoke weed until you get some. It'll be that much better when you finally do. Or stay awake until then. I hear at some point you start hallucinating. But I don't know, that might be torture, being awake twice as long without marijuana to smoke.
