I think we'd all be interested in your results!
If I were you I'd do 2 protein shakes, each with around 25g of protein, one at waking and the other between then and your breakfast. 50g of whey protein will be around 250 calories, so it won't take too much of a chunk out of what you can eat later on, and protein will keep you feeling fuller which can be quite helpful.
Not that you HAVE to use whey. People seem to forget that chicken or lean beef are basically pure protein. 8g of chicken breast is 260 calories, 7g of fat and 50g of protein. You could bake up a bunch of chicken and you'd be good for days.
