Thanks @Sister .... In the hot nights of the last month or so - I've tried the cold air (portable aircon) but it didn't really work either ..... I just needed to push the earplugs in further to hide the noise! LOL
I don't think I have the patience for recordings - I've tried counting backwards & forwards, pretending to already 'be asleep' (this USED to work) and also deliberately slowing down my breathing so it 'appears' I am asleep .... maybe the sound of the sea would work??
@SoldierCrab ..... Sarah Edelman's tapes are available on Youtube! Not sure someone talking to me (with my ear plugs in LOL) would work ....
It is a Work In Progress!! Hopefully one day, I'll sleep peacefully again!
