I agree with most of your points but the worst thing I can do is not eat enough. Eating too much may cause a little discomfort but will resolve soon enough. Not eating enough can cause me nausea and running out of energy, possibly even bonking and becoming more dingy than I already am.

When I was younger I did a 6 week tour. Started the ride @220 pounds plus the 55-60 pound bike. I ate 6000 calories per day and lost 10 pounds. I could burn food up almost as fast as I could eat it. I did find certain foods didn't work.

I've never done a double but when I used to do charity centuries I would stop at all the rest stops and eat. If I keep eating I don't have stomach problems. If I do a big climbing ride and don't eat I can get nausea. Once that happens it's difficult to recover.
