I Really Need To Chew My Food More

Warning - probably Too Much Information:
Kind of a nightmare, a couple nights ago, some food not going down, but I'm like, "Hey, I can still breathe, so I must not be choking." But it's really bad, and a swig of juice doesn't seem to help. So I sort of give myself the Heimlich and retch into the sink - that brings Cathy running. But there's still some food in there. Then, after another swig of juice, suddenly I can't breathe. Cathy sort of ineffectually tried to give me the Heimlich but I had more luck just sort of punching myself in the diaphraghm - so now I can breathe again, but there's still food in there. And I'm panicking. Hyperventilating. Freaking out. Finally, I throw up everything, and then things are okay.
These episodes have been getting worse and worse as I get older - but no learning is occurring. You'd think I'd slow down and pay attention.
