Not a Morning Runner

Is it that I am used to running in the late afternoon or early evening? I have been trying to switch over to morning runs this weekend and man am I wiped. I managed 1.55 miles this morning, going slowly, pacing myself, but I've spent the rest of the morning feeling like I need toothpicks to prop open my eyelids. I was pleased that I managed to run 6, 6, and 3 out of 17 minutes, though. But my legs are stiff and I'm not at all energised by it. Quite the opposite. Surprising, given I got a decent night's sleep last night for once. Maybe my body wants yet more sleep!!!
