Hugs and best wishes to you, Natalya!

From my own experience and talking with others, it seems to be pretty normal to have to get up to use the bathroom once we are past the age of 40.

Some things I've done to get more sleep -

Adjust your amount of fluid intake so you avoid drinking anything for a couple hours before bedtime.

Go to bed one hour earlier than usual. Even if you don't fall asleep right away, letting our bodies rest and relax can be helpful.

If your mind is racing with what might come at work the next day, keep paper and pen next to your bed and write things down. This allows us to put thoughts/worries away for the night. And then we can address them the next day.

I was also divorced. Before I met my current hub I would grab a big pillow and hug it for comfort. Add a heating pad if you crave extra warmth.

Good luck to you!
