A word of caution: We're told that people who take sleeping pills on airplane flights may experience memory loss if they wake up before the effect of the medicine is gone. People with traveler's amnesia carry on with normal activities but have no memory of their behavior for a few minutes to a few hours.

We once traveled with Molly and Norman Rockwell from Little Dix Bay in the Virgin Islands. When we were catching an early-morning plane, they seemed to have trouble collecting their luggage. Their Saturday Evening Post host spotted one suitcase being left behind and retrieved it for the grateful couple. We wondered whether they might have taken sleeping pills the night before, causing the senior citizens to be affected by traveler's amnesia.

Best to sip warm milk (one of our readers suggests adding cinnamon) or choose a short-acting sleep add when traveling. No need to risk traveler's amnesia and forgetting where you've put the purse or luggage.
