Juvie BP regurgitated 11 days ago, was told to wait 14 days

First, stop panicking, he won't starve right now. And yes, it's best to wait AT LEAST 14 days or more, following any snake regurgitation.

It takes time for snakes to replenish their digestive enzymes, & if you don't give them enough time to do that, you risk another regurgitation, & each time a snake regurgitates, there is a risk that they may aspirate (into their very life-essential lung!) and even die, so regurgitations are something worth preventing. Snakes also get dehydrated from repeated episodes, another serious risk!

I do agree that when you do offer him food again, size it way down (for the next few meals) to be sure he digests okay. Easy does it. And yes, until he makes a full recovery (is back to eating normally) you should also refrain from handling him.
