Dime to nickel size bites and chewing to mush before swallowing is key.
Some foods kinda reconstitute into a good stopper for your stomach opening.
Waiting at least a minute between bites is crucial as well. My NUT explained that it is good practice to cut your food into 20-30 right size bites before starting and put your fork down between bites.
Other than that, it is always good to talk with your doctor about anything that is going on, including, allergies or cold and flu, emotional times(crying can produce a mucus problem like when sick), calorie intake, types of food, exercise, and episodes like you just experienced.
