I agree, I have a hard time with it as well. However, I have noticed that if I force myself to workout a few times a week and get in a routine then I sleep better so maybe 10PM to 5AM is achievable...I just need to get back into that routine. :) But I think a lot factors in such as stress, sleeping comfortably, sleeping enough but not too much, etc.

Considering he has a 4 day work week, I imagine he gets a little more sleep Friday-Sunday to make up for it.

that may be because you actually oversleep. unless you're very young (<20yo), 7h of sleep is likely all you need, and anything less than 6h or more than 8h will leave you tired and lacking energy.

I could be oversleeping but I cannot really fix that. I don't use drugs to sleep or wake, and I don't wake via an alarm most days (alarm is for 7, I wake up at 6:40~55).

I could set an alarm for 5 am but I predict that I would be even more tired compared to my 10 to 7 schedule.

Try it for a week and see. What do you have to lose?

Alternatively, have some children and your sleep will not be the same for a long long time.

Ryan Carson says he has a 1 year old child, so I doubt he's sleeping through the night. :)

Why not go to bed later?

source?

No source. What he said is just broscience. You will feel tired and groggy if you wake up from an alarm in the middle of a sleep cycle regardless of number of hours slept.
