5 nights a week half a bottle of wine isn't an alcoholic. It's drinking too much.

If you're at a bottle of wine s night that's certainly too much.

You've got a poor habit that's all. Just put a system in of deferring first drink, going to bed s bit earlier i.e. Before the last drink, and ensure you have a glass of water and a cup of tea between each glass. That'll reduce the amount you drink by s glass or two.

You're fine.

My good friend, who IS an alcoholic, drinks a 750ml bottle of vodka in a night.
