Meat is just a bad habit. If you eat vegetarian for three months, just the smell of meat will make you gag. It's amazing how quickly your tastes can change.

The trick though, is to find really tasty and interesting vegetarian meals as a substitute. Plain vegies aren't terribly interesting. If you like spicy food as I do, indian vegetarian cooking has a lot to recommend it. But in fact there are lots of vegetarian recipe books containing great recipes from many different cultures if you spend a few minutes looking for them.
