Kevbo, just wanted you to know that sleep does make a huge difference. Like you, I went almost a week without adequate sleep (about 45 minutes at a stretch, never more than 2-3 hours a night). The first night I finally got 8 hours of sleep, I was surprised to feel merely "whatever" the next day. But once I got three nights of good sleep in a row, I finally began feeling like myself again. It's made a tremendous difference.
