well, since you're underage and obviously a little desperate, i will tell you the other trick of the homeless trade: listerine. high alcohol content, and has the advantage of not tasting quite so bad. i have never done either, but i know you can do the listerine, at least. and hey, do it enough and you won't have to brush your teeth anymore!

Let us alone. What pleasure can we have
To war with evil? Is there any peace
In ever climbing up the climbing wave?
All things have rest, and ripen towards the grave
In silence- ripen, fall, and cease:
Give us long rest or death, dark death, or dreamful ease.
--Tennyson, The Lotos-Eaters
