I just stopped. For me the key was to not try to replace it, meaning, I didn't eat veggie burgers or make things that normally contain meat by replacing it with faux meat. I just found some recipes that were designed to not have meat in them and started there. Since then, I've added things back in, like black beans in my tacos.
And no, I don't miss it. In fact, the last time I was around bacon being cooked, the smell turned my stomach.
For the record, I did it for health reasons and honestly have few ethical objections against raising livestock, outside of the large scale confinements. And those have more to do with the environmental impact. And for you hunters, go ahead, no issues with that either, just kill your quarry quickly.
