Due to the changes in hormones when exercising, by the time you FEEL thirsty, it is already way, way too late; you're already dehydrated. Putting water into your stomach then will cause some nausea. Try sipping a couple gulps of water every 10-15 minutes.
Drink a glass of water 30-minute before riding. This will give your body some time to absorb it. You won't immediately feel thirsty on the ride and won't need to drink too much.
As for the coffee + cereal case, it's probably not dehydration. Coffee won't dehydrate you until you start peeing 30-minutes later. And the dehydration effects of coffee is nowhere nearly as severe as... exercising and sweating away liters of water. In this instance, it's most likely just some discomfort and cramping from immediately riding after a meal on a full belly.
