During my early 50s after my periods had stopped for a year, I would sometimes go 48 hours without sleep ... I never felt tired, there was like a buzzing in my stomach almost like a bike revving up...when this feeling came on, sleep was impossible....I felt like I'd been plugged into an energy source and I just carried on throughout the night getting jobs done or sewing/knitting....I used to think...well, at least I have more hours to do the things I want than anyone else has! ( Not good if you're tired out I know...but I felt like I was on some super energy drug).
In my case very little worked, it was just another stage in this wild ride that has to be gone through...BUT....
One thing I have noticed...during the summer months I walk about 5 - 6 miles at about 7 pm. Not a jog, not a stroll. A good brisk walk. Without fail I always get a better nights sleep after a walk in the fresh air...come rain or shine or whatever. As soon as we put the clocks forward I will be going out again.... even a walk round the block might help...just to get you going?
Ps....if anyone does this by themselves make sure you alter your route on different nights....just remember to keep yourself safe....oh and don't plug your ears up with one of those music things ....keep alert keep safe, make sure you don't walk into any danger.
