In addition to this, and for those who live in places where this isn't feasible, I recommend some serious thought into the amount of meat consumption. I tried the vegetarianism thing, and basically felt awful the entire time. I don't know why, but I found I just needed some read meat every now and again. However, I learned I only needed a small fraction of what I had before. I end up consuming a moderate portion once a week opposed to one a day and an able to supplement the rest.
