No it does not suggest a level of dependency. I have a shower every time before I go out but that does not mean I have some kind of obsessive-compulsive disorder. Having a drink happens to be built into the way I personally choose to socialise. Not having a drink and not sticking headphones on happens to be the way I choose to do the gardening. Kicking off my shoes and putting my feet up on the settee happens to be the way I choose to watch the World Cup. I happen to find that having a drink is pleasantly relaxing and enjoyable and I don't go out to get sloshed. I'd rather do it than not do it. Implicit in your notion of dependency is that alcoholic drinks are intrinsically evil unto themselves, which they are not. There's more than a touch of puritanism in this argument.
