Hi marti - Personally, reading over your question, yes, I would say you have a drink problem. You don't suffer a hangover, because you drink regularly. During your work cycle ' you don't "really " crave it? You don't need a drink first time in the morning on your days off, how comfortable would you be not having any drink for the rest of the day?? 1 litre of vodca 5 -6 nights on the trot is a dependency. I think you already know deep down you have a problem, it's probably already presenting difficulties in your day to day life without doubt. Get some help before it really effects the ones you love, take care.
