There was not much difficulty for me, I mean for all of the 3 years of vegetarianism I did not consume any milk, or eggs. I would just eat cheese from time to time, and about two months ago I decided to stop and go fully Vegan along with cutting the consumption of refined sugars, etc. The only thing that might be hard is the prices of food , but again with my exercise schedule (which is riding my bike eight miles a day) my stomach has shrunk and I do not eat as much. So the little good food that I buy lasts for a few days. And I feel better than ever =) Do not know if this is of much help but there you go.
