My husband has claimed he has cravings for it when he's stressed, just like he has cravings for a cigarette (he quit years ago). He puts them in the same category. He rarely drinks, and if he does, it's at his synagogue... a glass or two of wine (and I mean a regular glass... not one filled to the brim!) I've described to him my cravings and he sees there's a big difference
Mine is a Pavlovian response at times... the sight of a bottle of wine makes me salivate. That's never happened to him.
I think he feels a temporary desire to escape, similar to an alcoholic, only he doesn't ruminate on it, salivate, lie and sneak around behind my back to hide it, etc. He doesn't plan to get in the car, drive to the store, and get two bottles to have enough to pass out. When I have cravings I see, taste, smell, feel the bottle and glass in my hand. I envision the drive to the specific store, the aisle it's on, and how long before I can open the bottle and pour a FULL glass.
