That is my routine: asleep by 9:30 (preferably), awake at 3:30 for a 5:00am workout. I usually wake up between midnight and 2 to get rid of that hydration I'm so careful about. I stumble downstairs where i've left the tub of Grow! on the kitchen counter with a shaker bottle.
The hard part (for me) is that moment when I open the fridge (I like cold water for Grow! shakes) and the light goes on. I can maneuver through the house in the dark, but that damned fridge light--curse its retina-burning lumens!--threatens to wake me up.
Do the middle-of-the-night protein.
