Hydration

Hydration is an important part of life, but so is precious gaming time.  To optimize both you should drink more water during your work day.  You save money on water you would pay for at home, the work day is then sufficiently broken up by bathroom breaks.  Then 45 minutes before leaving work stop drinking water.  The extra water you have consumed during the day should be enough to get you through the rest of the night.  You won't have to pause your gaming to get water or go to the bathroom.
