When I ate 1 gram of caffeine pills, I felt up and awake for a few hours, but then i felt sick for a long time, and eventually puked my guts out. Everytime I take caffeine pills I get sick, so I no longer take them.
And as for snorting, why would you want to do such a thing? Ruin your nose for a nasty shitty high thats just as effective as oral.
