Sadly, the level of drinking you've described, OP, is so common and has become so normalised in our culture that people fail to see how detrimental it actually is. Personally, I'd consider you a functioning alcoholic, as a PP has said. The stereotype of alcoholics being rolling drunk, losing jobs, reeking of vodka, hiding bottles and being unable to function is just that - a stereotype. Yeah it happens, but it doesn't mean that if you don't tick those boxes that you don't have a problem with alcohol. I hear people say over and over again that if they wanted to stop drinking, they could, they just don't want to. I've never seen anyone put their money where their mouth is and follow through. Not even being pregnant is enough of a deterrent for a lot of people.
You sound exactly like my MIL and it is widely agreed among the family that she is an alcoholic.
I say this from a position of being from a long line of alcoholics and battling my own demons with alcohol as well. Certainly no judgement from me at all.
