I drink a glass of wine every day - my partner and I both like a glass of wine with our evening meal. If it's a curry then we'll have a lager or a gin and tonic. Then occasionally, without even talking about it, we'll go 2-3 weeks and not have a single drink. Like you, I don't like being drunk, but I do enjoy the taste of wine. If someone came up with a good non-alcoholic wine that had the same flavour, that would be fine by me!
There are several stereotypes of an alcoholic: someone who drinks all day every day; someone who must have a drink every day; someone who needs to get drunk on a regular basis to blot out the hardships of the world, and so on. Whilst there are some alcoholics that fall into these categories, the person who only drinks at weekends can also be an alcoholic.
The question to ask yourself is - if you were told that you could never drink alcohol again, how would you feel? and are there situations that you couldn't deal with without a drink, i.e. has it become a crutch?
I saw a nutritionist recently - I looked at my diet beforehand and tried to second-guess what changes she would recommend. I had prepared for her to tell me to stop drinking, and I was OK with that. She didn't, but she did tell me to stop drinking my 2 cups of coffee each day, and that was something I found totally unacceptable! So I guess I'm a coffeeholic!!
