I am also a vegetarian for almost 15 years now ...
I have only been a Vegetarian for a few years, so I have a lot of respect for that. I do not fill up on veggies, however, I simply took meat off the plate. Everything else is the same. I know the meat industry is here to stay, I'm not trying to change the world. I just can't justify eating meat. It's not necessary to my survival, so I finally gave it up, completely.
