I have a container of sugar cubes, but I haven't needed them in awhile.

I can kind of sense the oncoming Vitamin N overdose, so I just stop smoking.

I used to make it a goal to try to nub everything, but now if I'm not enjoying the cigar for whatever reason (nausea, my weak ass palate getting overloaded, bored with the cigar, tired of keeping a troublesome cigar lit, etc) I just stop.

I guess it's kind of "wasting" X inches of cigar, but IMO it should be for enjoyment first.
