Ha, I just responded to another of your threads - perhaps we are on the same wavelength.
For me it's missing what never was - I never was that kind of responsible, fun, normal drinker. My wife is like that - she would never think to ever have a drink alone, often leaves half a glass at a restaurant, etcetc.
So when I see others drinking I find myself with the pang for the booze - but it's bs if I think it's a wish for anything other than oblivion.
