@OP, you could be talking about me, and yes its a problem. I've cut down massively at the moment because I'm on a diet and that works, but as soon as my weights down I'll likely be back onto 4 cans 5 / 6 nights a week. I don't feel like I'm a fully blown alcoholic, but I do have a habit that is very unhealthy.
For me its only really started since having kids, prior to that I'd go to the pub and have a couple a couple of times a week. But now I'll go and get 4 cans from the corner shop, because, well, they come in handy 4 packs, and then I'll drink all of them because if theres a solitary can left in the fridge, I'll want to get it some friends the next day..... And then I go and buy 4 more the next day anyway.
As my childs got older its getting easier to go out and do things in the evenings at the moment, rather than sitting watching TV with a beer, which helps, so I'm going out and doing exercise in the evenings, doing housework later, trying to change my habits that way. And mostly its working, but I have doubts about being able to stick to it long term, and this worries me.
