There have certainly been a lot of books and articles on the subject of living a dairy-free life. I love cheese, but I'm also having it less often. You can find a lot of great dishes that don't contain dairy, and adapt many others. Soy cheese is perfect for pizza. In pasta, I've used dairy-free Parmesan, and it's excellent.
Soy milk is also great for baking.
When it comes to baked goods, I'd suggest doing some research on Italian breads and French baking. Many of these items contain no dairy. Muffins can also be made dairy-free. For now, try increasing the fruit to make them moist, and look for a dairy-free muffin recipe in January. I would also find a doctor who is part MD, part holistic practitioner.
