Read the Adobe Photoshop manual chapter on color rendering engine selection. That's enough to put anyone to sleep.
More seriously, here's a good one to try: get some background music CDs, i.e new age/ambient type stuff, whale calls whatever, that will probably get you relaxed enough to go, failing that, get hold of a recording of a single tone, that usually works like the drone of an engine at a steady RPM does when it puts you to sleep, like it does on long aeroplane/train journeys and (somewhat dangerously) a car engine note when cruising on a motorway. You could also try altering the temperature in your house, I always find warmer temperature make people drowsy, which is why I knock the heating down a bit in training rooms when I am teaching people!
You are getting sleepy....
