I had a spell for about 6 months where I would wake up at 4:44 am about once a week. When I was a kid, stock car racing hero was Wib Spaulding, who drove car #444. Figure that one out. It was like the alarm was set. I have sleep apnea and use a CPAP machine and it has been a Godsend for getting deep sleep for about 15 years now....except when my prostate drop kicks my bladder to get up and pee. Once a night, used to be 3 or 4 times a night before CPAP. My dad, who lived to be 95 years old, for as long as I can remember took a good strong jigger of Jim Beam right before bedtime every night. For his 90th birthday we bought him a case of Beam, when he passed 5.5 years later he had one bottle left unopened.
