Q. I shall be spending more time in the company of newer acquaintances in the West Country and would appreciate your advice with regard to a resurfacing problem: narcolepsy. The condition is the source of much embarrassment and I find myself at pains to explain it upfront. (People may infer spurious connections due to limited understanding – that is to say ‘narc’ is now much more closely associated with narcissistic tendencies or worse, narcotics.)
