It is always a good idea to go ahead and call a meal finished when you feel done. Same with a smoke; if you are no longer interested, or not enjoying it, stop. While I like the idea of smoking to the heel as good form, and good for the pipe, it should never be at the expense of the experience. Learn to pick the tobacco that you can burn through in that pipe, on that occasion.
