Doing my best to be a vegetarian

At this point, doing my best means that I've given up eating anything which has ever walked on land. I still eat eggs, fish, and shellfish. I also eat dairy. I'm not vegan by any stretch. However, since I started the vegetarian journey a few months ago, I've lost about 25 lbs and I'm generally feeling much better. The best part of the weight loss is that I really have not changed my habits to include a lot of exercise, which I can't seem to fit in regularly thanks to my terrible work schedule.
