Earlier quoted context omitted.
For me, If I get all the sleep I want, I'm lethargic and unenergetic, but if I get less sleep I'm tired all day (but strangely more energetic). It's like there's no happy medium. I wonder if anyone else has this problem, and if there's a solution.
Do you exercise most days? Do you at least a similar wake up\sleep time for a month? And another obvious about drink enough water\food? All have a huge impact for me. I can go on much less sleep when I do hard exercise that day.
Recently, though, I started a linear progress novice strength training program (Squats, Dead Lift, Bench Press, Overhead Press) - three times a week for 40 minutes. My sleep patterns immediately shifted, and I am incapable of waking up without at least 8 hours of sleep on off days, and 10 hours of sleep on the days that I lift heavy.
For the first time in my life, ever, I'm finding myself going to bed at 10:00 PM at night so that I can get up by 8:00 AM the next morning.
