A good shower before bed is the best thing you can do. It gets the smoke out of your hair and off your hands, cleans out sinuses that might be irritated.
We all love cigars. When I'm in the zone, cooking up ribs or watching a game on the patio, I'll have 2-4 in an afternoon evening. But when I'm done, I'm done and don't want stale cigar sticking to me. I have a beard so maybe that's what bothers me, but a good shower always helps me.
