you need to really be careful with milk. Regular milk is filled with lactose. This can be very bad, lactose causes insulin spikes, so depending on your goals you really want to adjust your milk intake accordingly.

Also, as with anything "fat free" there will be extra carbs, usually in the form of sugars.

If you are bulking, and have a fast metabolism, this might not be a problem. but if you arent, you will want to go with the water.
