I read WDDTY vol 15 no 11 with great interest. Pneumonia is something to be avoided - my wife died of it.
With regard to sleeping pills, I would like to draw your attention to an old-fashioned drug I have been taking for about 20 years, with no apparent ill-effects.
I don't sleep well, and after a trial with benzodiazepines, which gave me hallucinations, my doctor gave me Welldorm, which contains chloral betaine 707 mg. Chloral is also known as a 'Mickey Finn'; it is combined with betaine, a useful compound containing methyl groups.
I take two when I go to sleep, count to 100 and seldom reach the end - which means about two minutes. This usually carries me through to 4 am, when I take another to last me until my alarm-clock goes off at 7 am. I'm 93 and don't suffer from any illnesses. - A.J.S. McMillan, Bristol
