Training taste buds.

Something I forgot to mention but it's important: purge.

Every few puffs, purge the cigar. You'll find that it helps clear out a lot of the charry/burned tastes that can occur as a result of lighting or re-lighting.

Purge, then sip—then retrohale. Try that and see if it doesn't make "nose smoking" a whole new experience for you.
