It's worth noting if you're fighting sleep or fighting attention span. If you have no taken care of your sleep/stimulant/nap issues, I wouldn't even start on your concentration and productivity issues. For me, that means 8 hours of sleep and often a 10 minute nap after lunch. Once I have that down, and interesting problem can keep me going 8-10 straight.
