[@PARTYManagementARG]

if you can sleep whenever you want, even after drinking stimulants, is because you are living "tired". Your body is always yearning some sleep. You are living under your potential.

[@WeighedWilson]

When I was a teen caffeine gave me a nice jolt and it didn't interfere with sleep. As I got older caffeine started to interfere with sleep. Maybe it's a case where your tolerance goes down with exposure and Lex hasn't hit that level yet.

[@WilliamParkerer]

​@@WeighedWilsonCaffeine always interfere with your sleep, it's likely that you don't realize it when you're young. When I was in my teenage years a slight sip of coffee would make me stay wide awake in the night. Lex was probably not realizing this too.

Lex, I agree, ruminating on the ideal number of hours sleep one should achieve is incredibly stress inducing for me also.

[@naptime_riot]

Less sleep means I am using up my lived hours while my body is younger. If I sleep twice as much and live that much again as long in my twilight years, what have I gained but sunsets and back pills?

[@fishbrainLTD]

I got Narcolepsy bro I can get as much sleep as I want, my hypocretin are gone, which means it's rare that I'm rarely ever "awake". People think narcolepsy means you just randomly sleep. It's more like... The majority of your time is spent ready to fall into REM, whether your awake or asleep. I would check for Narcolepsy if you're falling asleep and going directly int REM sleep, that is a marker .

[@fishbrainLTD]

Also, anything weird happen when you laugh?

[@fishbrainLTD]

The diagnostic test for narcolepsy is simply: - can fall asleep in under 5 mins, in a sleep study, many times in 1 day Type 1 Narcolepsy means you have Cataplexy (when you laugh/strong emotion, you lose muscle tone) Type 2 Narcolepsy is without Cataplexy. The common signs for all narcolepsy is: - constant sleepiness - sleep paralysis - hallucinations (before/after wake) -sleep attacks (unable to stay awake) - sleep disruption But I would just ask yourself: is your rem sleep overactive? Do you go into REM in your 20 mins naps. That's a solid way to think about it. Somehow I get the feeling you have it, just from seeing you talk about your sleep but maybe I'm projecting haha But I tried fixing my diet too bro, my habits, all the self help bull, sometimes your brain is just different and you gotta work with it not against ha

When I switched to Healthy Keto+IF/OMAD, I started to sleep max 5h, usually 4h and I felt totally fine, actually well-rested. Before I slept as long as 14h, with an usual length of 10h a night and never felt rested. Not even on 8h. First 4 years of Healthy Keto+IF/OMAD I took no naps. Now, I take a 10-20min nap 2-4 times a week. But: each and every time I ate more of healthy carbs, when I went over 50g healthy carbs, I slept longer that night and maybe the next. No carbs, or under 20g(for me)=5h well rested sleep.

[@jac9301]

You sleep less because your cortisol levels have risen, unless you have a genetic predisposition towards sleeping less you can't cheat sleep, carbohydrates making you sleepy is suggestive of poor insulin sensitivity.

[@jamesbondisamonkey]

Longevity is not really the best metric for maximizing life utility. If you spend the majority of your years eating lettuce and sleeping , you haven’t really lived at all. You need to multiply each event by how much excitement , adrenaline , and factor in your particular ability in the moment. A man hitting a golf ball 250 yards is not the same experience as one hitting it 300. Banging a hot woman trumps banging an ugly one. Eating sushi trumps eating lettuce. Longevity is a meaningless metric. It’s about overall utility gained based on your particular makeup And abilities that reflect maximum life lived.

[@bobspurloc]

@@tomjwjss if you choose to go to sleep 5 minutes later every few nights depending on how you feel extending the 2 days to weeks or months. to an eventual comfortable stop point is that stressful? no. what if I kept u awake nightly increasing 5min every night no matter what... that is stress. the amount of sleep a person "needs" is what they have learned throughout their life. it has nothing to do with what another person needs. so a blanket statements of johnny needs 8 hours so susan needs 8 too. and if susan doesnt get the same amount of sleep that johnny does. it 100% does not mean johnny is healthier. it only means one person sleeps longer than the other. sleep deprivation is how you get a rat to not sleep which is high stress. and therefore the statement is invalid.
