I may be afflicted by it. I do constantly check my various in-boxes frequently and see what's going on though I control the urge to respond immediately. I have tried following the prescription but have relapsed in to my old ways.
So the solution lies in not monitoring your mails constantly but instead setting aside a dedicated email reading times to catch up on messages, and giving yourself time to reply.
How about you? How do you handle the deluge of emails coming your way each minute? (Of the six trillion sent in 2006, some ought to have been for you).
