Reba,
I was brought up veggie by veggie parents and ate meat for a few years in my teens (actually only chicken, fish, and turkey) then switched back b/c I was just too grossed out by cutting chicken one day.
I converted my husband while we were dating and his family are BIG meat eaters--which bothered them a lot!
But he felt so much better and noticed such a difference in his energy level, allergies, and ADD that he never wanted to go back. The few times he did eat me after that (to please his mother, ugh! that woman!) he felt so terrible that it wasn't worth it.
We've been working at becoming vegan (for health and environmental reasons) since about April and have never felt better. My husband actually lost about 40 pounds! Doing nothing except giving up animal products and cutting back on processed sugars. We both feel so much better with no dairy or eggs, and on the few occasions we've have (oh, pizza and ice cream!) we've paid for it intestinally!
I also read Dr. Fuhrman's "Eat to Live" which precipitated the change to veganism and confirmed what I had felt for years about vegetarianism.
We just feel so much better, have so much more energy, and love animals the environment and feel great about making this choice for those reasons.
Hope this helps,
Mattea
