Are you hiding a secret high tech city behind a forcefield?

I am exactly the same way. I feel fine sleeping for 4.5h a night for 5 days if it's the right 4.5h, and I'm allowed to get up at about 11.

Force me up at 5 for three days in a row and my mind is jelly and my muscles are lead, regardless of how much i've slept

Try this one, my latest 5 shift rotation:

W1: m,t:off w,t: morning f,s,s:12h night

W2: m,n:off w,t:evening f,s,s: off

W3: m,t:morning w,t:night f,s,s:off

W4: m,t:evening w,t:off f,s,s:12h morning

W5: m,t:night w,t,f,s,s: off
