Dazimae -
My H used to eat like horse. Now, he never eats. I guess he eats lunch at work but never dinner.
On the weekends, he won't eat anything all day - sometimes dinner if he's not passed out yet. He knows when we eat dinner and I always keep frozen pizzas and stuff on hand in case he wants to fix something. Other than that, there's nothing I can do about it.
I think that either they like it because they get more drunk when they don't eat or because they are drinking, they aren't hungry.
