Yes, I agree it is not for everyone but it is good to give it a try! No any member of my family is vegan or vegetarian if I don't count my sister. It is just not good for them and I am totally ok if they are not. Sorry to hear your body refused it...maybe it was just very simple for me and I haven`t experienced how different it can be for the others. My boyfriend is a meat eater and he is very healthy too! We are both but we have totally different diets...
