I have no scientific evidence to back me up here, but I've been downing pro-score shakes at 3 AM for quite a while now and I really don't notice a difference in how I feel during the day in terms of drowsiness or mental alertness. I try my best to minimize the wake up time by having the shake all ready to drink, so I just go to the bathroom, down it, and fall back to sleep (virtually instantly btw). And this is coming from someone who doesn't really get as much sleep as I should anyway (usually around 6 hours while 7 seems to be the ideal for me).

I do like the idea of letting my need to urinate be my alarm clock though... I should experiment with downing LOTS of water before I go to sleep.
