A small piece of chocolate if I've over done the nic hit. Great tip about calming tongue bite with sugar. Sounds strange as the sugary blends are the ones that typically bite!
It's never even occurred to me to eat in the midst of a smoke. I once made the mistake of eating a couple donuts not long before smoking and found that the sweet and fat of the donuts coated my tongue such that the smoke was nigh on flavorless. So if anything I'm more wary of what I eat if I'm planning on smoking soon after.
