it´s been a while since i adopted a vegetarian diet, but lately i took it one step further and stopped eating anything that comes from animal exploitation, like milk, cheese, eggs...
i saw a documentary about the subject that had a very strong impact on me, and it does affect everyone that sees it. it is called "earthlings" and it is a great statement about mankind's dependence on animals for food, clothing, entertainment and use in experimentation.
