I have this, but a 20 minute nap or a walk to 7/11 usually fixes it. What happens to anyone in this thread when they try that? I will normally feel better and more awake after doing something like this. That, of course, may well have no effect on how productive I am. Optimising for 'feeling good while working longer hours' should not be the aim. Optimising for 'producing the most useful stuff in time period X' should be what we're after. Earlier in my life I could happily sit in front of the keyboard for fifty hours a week and feel fine. However, when I started measuring what I produced I found that I was more productive if I spent about 30 hours in front the keyboard. If I had a time machine that's what I'd tell my 20 year old self. You can do more by spending less time in front the keyboard, which has the happy side effect of giving you more time to do more away from the keyboard.
