You are on the right track but do it for yourself and you will succeed. The health benefits of not eating meat or liquid meat (dairy) far out weigh any reason you could possibly think of. No more worrying about cancer, diabetes, heart disease, your weight, and the list goes on, not mention the positive impact on the environment and the animals. Read The China Study by Dr. T. Colin Campbell, watch the healthy lifestyle dvd's and it will be put into perspective for you.
You will eventually lose your cravings for animal foods and crave even more varied vegetables. The variety of foods you will be introduced to will amaze you. I went vegan a year ago after reading The China Study. I stopped eating all animal foods over night and I have never looked back. Stop thinking about the negative impact it might have and focus on the positive impact it will have on your health and the health of the planet. Your family won't make fun of you when you are fit and energetic! There is also a great DVD from the Vegan Gal. It is made for people starting to make the change like yourself, check out vegangal.com. Enjoy all the new foods and forget about how cheese taste and think about this; Milk is one third MUCUS, cheese is concentrated milk. Enjoy your cheese!
