Think of it this way. Why can't you just go and write the code to solve all the big problems in one day? Because of the context switch between problems. Each one requires more energy to think about and switch to. Each night is like preparation for the next big context switch. One thing I do that helps is I set little 10-30min timers and say "I'll do this in this time". Gaming your time helps a lot. But things like coffee and drugs are just taking energy away that you would have later. So it's not a net gain. Sleep/naps are the best reset mechanisms IMO.
