I talked to his wife, Dee, a couple of hours ago. She suspects it's his reflux acting up again, since he's out of the medication for it. (Apparently the insurance stopped covering it. Ugh.) She and their son were away for a few days, and he may not have been as good as he should have been with what he ate and drank!
So I think she's more annoyed than anything else, but we'll wait until tomorrow. Hope all's well.
