Is it just cow´s milk you can´t have? Soya milk is quite nice especially the flavoured ones. There is a good cook book called Healthy Dairy Free Eating by Tanya Carr. You will be able to get it on amazon
If you go to your local health food shop you will be surprise how much dairy free stuff there is. Try SOYA products my friend has a dairy intolerance and she just uses all things made with soya, it will become the norm after a while.
