Veganism

Are there any nonvegans (or people who have been vegan/vegitarian)that have any information about veganism? I want to know how meat and dairy effect your body if at all and does it make you feel different. The reason I ask for nonvegans is because I've only gotten biased answers from vegans. Im considering going vegan but I just don't know enough about it to commit. Any info or tips or helpful comments are appreciated!!
