What worked for me is, I did a "trial". No pressure. Just said I will do this for a week or two and then stop if I want to. After the trial, I felt so good that I didnt want to stop. You might find the same. Now mind you I have only been vegan for 2 months but I can say I dont have a desire for those foods anymore and in the incidences where I do have a craving for something, which has happened a few times, I came here and got some great ideas. Example....needed some buffalo wings! Was suggested on here to try cauliflower instead of chicken...totally satisfied that craving.
Like Emma said, "just do it"! See how you feel...
