My two male sibblings, my father, and I all sleep what could be described as 'poorly'. We sleep reasonably well, but not long. I think our average is around 5 hrs per night. We are all in good health (I have apnea and consequent AFib, but both are being managed). We are all in our late sixties, and our dad, who gets up at least twice each night to pee, and also has apnea, is 93. Our average IQ, not that it means much to argue with, is about 125. Or was when we could divide the score by our age decades ago. 🙂

But, we all have different genetics, habits, propensities, and desires. One size of 'anything' doesn't fit well for all of us. My wife sleeps almost 11 hours a day with naps included. I get between 5.5 and six hours on decent nights; no napping. If you are bothered by an apparent lack of sleep, try melatonin, less than 5mg if possible, but rather infrequently so that it doesn't lose its potency for you...maybe two nights a week. I have recently been prescribed Zopiclone because I was sleeping very poorly due to complications after a recent atrial radio-frequency ablation to isolate my pulmonary veins (it's a long story). My GP said take one pill for two nights, then stretch them out. I got five tablets. My pharmacist advised me to halve them...due to my apnea. I tried a half one night, the first night, and did really well. Then, for the past six weeks, I have only used one quarter tablet, using a pill splitter, and that works almost as well. Following my own advice, I only use it twice a week, and only when my backside is really dragging. I'm over the hump and just went a week sleeping well without anything, not even melatonin. My point is that you should use some tools when you really must, and fight like aitch to get them off your waist...if you follow. Discipline yourself to endure some bad nights, and then resort to one or the other...or both.
