I think i read somewhere....quite awhile ago so pardon me if I'm incorrect...
Something like there might be a couple different kinds of alcohol addictions and probably a mix of those also.
One would be the chemical addiction the kind where you need more and more and go into detox withdrawals if you don't have it.
Another would be more of an emotional addiction - feel the need to have it but not really a detox or withdrawal happens if you don't.
I guess it also depends on if you are sipping those shots spread out over the evening or slugging them down real fast - to get a buzz on...
