Very nice guide ^^b. I like it, though 1-2 gallons of water... kind of sounds a bit overdoing in my opinion.
1 gallon of water is can be done EASILY. I drink 3 liters during my workouts, that's about 1 liter short of a gallon. And during meals I drink AT LEAST 500mL of water (as much in a water bottle)... that's another 3 liters during the course of the day adding up to about 1.5 gallons already. Then including all the water I drink randomly, it equates to almost 2 gallons. If you are drinking water regularly, it should not be a problem getting 1 gallon of water daily, which really isn't much at all..
