It is certainly a problem;
I have had the problem for a number of years and now when I wake up in the middle of the night, or can't get to sleep, I have a cocoa, and pray and read the Psalms.
Time with the Lord on the 'night watch' the same as the monks in ancient times that I have read about, I give to the Lord.
I also pray every night for a good night's sleep, since I realized the importance of this time.
Bed time is ideally 10.30pm, certainly lights out by 11pm. I read in the Bible that sleep is a gift from the Lord,
Psalm 127
2
It is vain for you to rise up early,
To sit up late,
To eat the bread of sorrows;
For so He gives His beloved sleep.
Last night I slept! and today I feel so good and thank the Lord for his blessing.
