I don't seem to have this trouble. Diet and preoccupation seem to be pretty much the only factors that affects whether I sleep. Thus I must not eat after 7 if I want to fall asleep by 11. And almost nothing wakes me. Someone was stabbed to death on my street once and I slept through the whole incident. Provided I have followed the eating rule, I can fall asleep to any music or stimulus, even violent atonal C20th music. I fully expect to die in a fire someday.
I am fortunate. I fall asleep when I want to, which means when I am tired. I sleep lightly but it never really bothers me if I wake in the night [or if I am woken] because a cup of tea usually sorts me out. I wake when I need to. How dull.
Not really - BUT - come on, Dr.Q+ - you are within sight of the line (or at least in line of site.) You can make it ... deep breath ... push ... push ... only a bit to go ...
I'm afraid that Doris_Newbold and ffiish are about to lose a bit of well earned dosh, Doris though having just made the finishing post.
