ARRRRGGHH!!!

WHY do I feel the need to draw something IMMEDIATELY when I'm in bed and just about to fall asleep? It's half-past midnight, I'm freakin' exhausted, and yet the insane little voice in my head (insane voice in head, meet world. World, meet insane voice in head. I call him 'Charlie') can't stop coming up with ideas and the compulsion to create. Which really sounds so high-falutin' when I see it written down. Why can't I be this productive during normal hours? AARRRRRGGGH!!!
