20lbs in one day is the most I've ever eaten/drank. No way I'd even consider doing it every day, you would be backed up pretty badly...
And the more food that's still inside you from yesterday's meal then the less room your stomach has to expand. I'm sure some of you have noticed that during a big meal you might have to get up to use the restroom (I assume because your stomach expanding is pushing on your colon) and it's never a healthy looking result.
I think 10lbs or so a day would be doable though.
