No books or threads but a couple of basic points that bear repeating:

1. Take regular breaks. I take regulation breaks of at least 10 mins each hour and straight away after a big suckout.

You might want to investigate the working conditions that air traffic controllers operate under, they have a similar job in many ways.

2. Work out, pref early on, to get the energy flowing. Run, swim, anything. I find I play best during the early hours and get gradually worse as the day goes on.
