Drinking plenty of water and coffee

Today, I know, should be the 2nd most difficult day with tomorrow being the worst. That's until my body starts burning fat instead of sugar - it's when you feel most hungry.

A lot of people think that hunger builds and builds, it doesn't, it comes and goes in waves. While still burning sugar then lack of energy can be a problem, but once it gets into fat burning mode the amount of energy goes up - and up. So that there's enough energy and adreneline to go hunting and not get eaten.
