Do you miss meat?
How hard was it to give up meat?
How hard was it to change you diet to still receive the protein you need?
I'm mostly looking at it from an ethical standpoint, but that is not the focus of the question. (It's damned hard to find a company that will grow and process animals that aren't extremely cruel about it.) However, I'm looking at losing weight and adding muscle, and so I am going to want to maintain a high level of protein-to-fat ratio.
This may just involve severely limiting meat intake to companies and places I know can treat their animals correctly.
