I am sorry that this has happened OP! I'm toying with giving up alcohol or at least trying to cut down. I'm also not an alcoholic-but I know I drink too often.
For me It's the fact that I live alone and spend a lot of time alone.
I have a good thing with my local pub. I am one of the regulars who sits at the bar. It's good to do, I've met friends in there who I've employed (I run a small business) as contractors, I take my dog, socialise-It's fun, and It's fine. But it has gone from one to 3 nights a week. The dog even nags me to go there now because he gets a lot of attention and fuss, and will bark at me to go. I know that's what he wants because if I dress in 'pub clothes'-he gets excited. If I just throw my scruffy coat on to take him for a walk he won't come!
If I go to the pub less, I open the wine at home.
I work, run and other exercise almost every day, do my business on the side, I'm currently writing a thesis-but ultimately the only 'me' ' I do is drink, it makes me happy, it is my indulgence, something I do as my 'only vice' if you will.
I don't want to stop going in the pub because that's the only time I really see anyone!I do go to the gym but It's usually just me and a couple of body builder blokes- (very 'old school' gym) they're nice guys, we say hello but that's it.
If I gave up the pub I'd not talk to anyone other than the occasional chat with a fellow WFH colleague. If I gave up having my indulgence of having a wine at home of an evening what would I do instead? I've tried just going to bed early (if I do drink It's never until late on, I do this on purpose so that I can't have much as I know I have to go to bed to be up for work)but I just don't sleep early or if I do I wake up at stupid o'clock. It's like that for me.
I have stopped going to the pub any earlier than 21:30-that way I simply cannot fit many drinks in before it closes so I've cut back that way.
When I was with my ex and we lived together I didn't do this-we did go out for dinner drinks and drink too much sometimes, but it wasn't anywhere near as frequent. And if we drank at home it wasn't as often and I was happy to not as I had someone there to go to bed with and talk to. Now, It's just me. As I've said it isn't alcoholism territory but it never is at first, is it?
Sorry just realised I am derailing your thread!
As others have said, maybe it is just a case of more time. Could you find an 'eveninghobby'? Reading or indulging in a new genre of TV even?
