Try yoghurt. It is a kind of dairy product too. Otherwise you can try eat cornflakes with milk, so that you won't feel the taste. Or, prepare some desserts with milk like add milk in to pancake powder to prepare pancake, add milk into "tong shui", etc. You still need dairy products since they contain many other vitamins (like vit. D, vit. A, etc.) other than calcium. Do try!
