One of the key things here for those not used to cooking for themselves is to look at ingredients on seasoning blends if you use them. Many, if not most, seasoning blends that you buy will have salt already in them. I can't tell you how many people I know who will use one of those and add salt while cooking, and then add more salt when eating.
The second dietary change I made was reducing added salt. It's like people say about quitting smoking - after you get over the hump, food tastes so much better.
While it might work for some people, and for me with other cravings, alcohol is just too accessible outside the house for this to really work. I work directly next door to a liquor store, and live across the street from another one. Attempting to cut it completely out would likely lead to a binge event after a bad day or whatever, which will be harder to recover from than if I incorporate a moderate amount into my diet. There's a great store with a massive craft beer selection that lets you buy individual bottles. They're next to the market I usually go to, so I'm thinking that on days I go to the market to buy food for dinner, I can go next door and buy one beer. This acts to satisfy my desire for beer as well as reward myself for going to the market instead of stopping at one of the fast food joints on the way home.
Spoonless, I'd like to put forth something for consideration. The best way to deal with beer might be simply to not buy any. I think people put too much emphasis on willpower on not enough on working with basic impulses. IF you keep something in your refrigerator or pantry, you're probably going to eat it. The more accessible a food item is the more likely you are to consume it.
