If I could just add, this could be a small gradual process. Your body will need the time to adapt to the changes, and therefore, taking it slowly and gradual you will be able to make it through. The Chinese and Vietnamese sects of Buddhist do in fact eat meat. And, what can make things hard is knowing that meat for sustenance now a days, all is killed for the one eating it.

But, I am sure that with the proper meditation, and a slow process, you can incorporate the change in your life.
