Wow people, enough with 'try to control it', 'can you drive after 1 or 2, or 'that's not enough to qualify as a problem!!!
19 knows he has a problem and needs our help. I could and did drive and finally got nailed and blew a .25! .08 gets you used in Texas.
I am glad the poster has the moxie and sack to face this now before he goes spiraling down that same rabbit hole that I almost never came out of.
19, I recommend AA and see a qualified shrink. And keep posting here and read all you can. Don't try to control or manage what you know is a problem, it most likely will not end well.
