if you can get hold of this while you're young you can save so much heartache for yourself and your family. i didn't sober up until i was 41, and by then my life was in shreds. alcohol will kill you as happily as heroin or meth. it's a long, long painful death though, and it happens by degrees.
please, at least educate yourself now. the more i learned about alcoholism, the less i 'enjoyed' my drinking.
so, yeah. don't be me. make a plan and resolve to be well. your future self will thank you.
