When I can’t sleep, I turn around and sleep “upside down” - moving my pillows to where my feet were beforehand, and my feet to where my head was beforehand - and I stick with that for a week or so. It gives me a week or so without insomnia and then wears off, so I have to turn myself back around for the next 7-12 day period.
Admittedly this could just be a me thing, but let’s put our faith in this method and let the power of placebo effect take hold. Boom, minor bouts of sleeplessness are cured.
What are your own examples of this?
Honestly with hiccups I concentrate on what it feels like to be about to have a hiccup and then I don’t do that. I haven’t had more than - few hiccups in a row In years, and now I’ve taught my wife to do the same and she can kill them off mentally too.
