You don't have to eat for 8 hours. Just spike the carbs a few times in those 6 to 8 hours a few times. If I'm hungry it's a lot. If I'm not its not a lot.

Example: 3 pm rice crispy bar and milk. Dinner, let's say a chunk of beef, a scoop of Mac and cheese, maybe a bun. Closer to bed a treat like cheesecake or a slice of pie with milk. Sometimes it's more or less.
