It sounds like you don't want to hear our answers yet, and truly accept them. To just add to the sage words others have said above about why this is alcoholism, I will just say that you seem to have a LOT to lose- future career (military or otherwise), parents, girlfriend, legal rights (ie driver's license)....your life or someone else's....play those tapes through as we say, and what do you see happening if you continue drinking, lying and avoiding, for each of these people/entities?
Imagine what you think NOW is the worst that could happen and know that many of us would tell you from our own experiences and those of other alcoholics we know, the "worst" could be way worse than you ever possibly imagined. I hope you don't go there.
PS 8 beers in a day is too much. That part is bothersome, too.
