Hi and welcome back
I dunno - maybe you were an end stage alcoholic and you were just lucky - maybe you were an end stage alcoholic and you felt pretty rotten to begin with so you didn't notice the difference, or maybe you weren't an end stage alcoholic at all despite what the web MD sites say.
The important thing is not to doubt your condition. Abstinence is not the same thing as control.
I took my last drink in 2007 but if I took another drink tonight I fully believe and expect I'd be back in the addictive alcoholic madness again some time soon.
