Changing my lifestyle? Maybe.

I have been doing some research lately on the meat industry. I never realized until just recently the normative fashions in which these animals are slaughtered. I always assumed that they killed the animals quickly and pretty much painlessly. But I now know that this isn't the case.
I really would like to become a vegetarian because I have seen the incredibly cruel mechanisms in which all of the main meat providers kill these defenseless animals, but I don't know the first thing about completely changing my eating lifestyle around.
Any thoughts? Anyone out there who has done this that could give me a hand?
