When I was a teenager still living at home, my parents decided to go vegetarian. I ate no meat, fish, or poultry for eight years. Although, I kept milk and eggs. The biggest hurdle is knowing how to cook that way. Some of your usual recipes will have to be thrown out, because if you try to replace your favorite ground beef recipe with tofu or one of the other substitutes, you'll be disappointed. Try learning ethnic dishes that were created as vegetarian foods, indian, chinese, japanese... many of these dishes started out vegetarian because meat was just too expensive for them, it was only when westerners began eating it was meat added. You'll need to learn about complete proteins, and how to combine foods so that you can get what your body needs. With that said, Europeans, and Americans especially eat FAR too much protein than their bodies actually need. Humans were not designed to eat meat at every meal, it was just too difficult for us to get before we started domesticating animals. It's not as difficult as many believe to get complete proteins in their diet, and all that your body actually needs... not what we've been led to believe. Combing rice and beans, salad with chickpeas, peanut butter on whole wheat bread, hummus...
I say go for it P, it's not nearly as difficult as it may seem, and it's a very good thing to do, not only for your own health, but the planet's as well. It's also gotten a lot easier since I was a vegetarian to find vegetarian food at restaurants.
