I use unflavoured soy protien powder to make my drinks.
However, when I was shopping around I visited a local independent health store. They had tubs of the protien shakes of varying carb contents. They also did individual sized sachets for £1.50 a throw. A bit pricey, but a bit easier to carry around if you are going away.
