Hi nonnie -my first post! I understand completely about sleeping frustration. We have a very draining family situation which means we are both constantly exhausted. My DH goes to sleep anywhere and easily at night. Here is my list of surviving disturbed nights and dropping off.:
Dropping off: try not to engage in conversation about tomorrow and watch something with good story value in tv but not the 10 o'clock news!
Sometimes I have a cup of warm milk plus tiny whisky.
Best thing is I've changed what I read before tucking down: nothing tense, eg have re read all of Jane Austen, or have re read my favourite books as a child -v comforting . Or, I must confess -an old M&B book read it all day and you'll fall asleep I promise!
In the night I know I am going get stewed quite quickly so first I go to the loo, I look out at the night sky, I make sure the windows are open ( tip from a novel) and at 3/4/5 a.m.I search for a comedy or semi interesting programme on radio iplayer put ear phones in and I find myself waking up after a deep sleep several hours later. I only take pain killers, (knees) nothing else. It's something to do with controlling and beating the anxiety of knowing that your sleep will be disturbed. I hope that helps.
