Oh my goodness... That sounds terrible 😬 why are you on 2 hour sleep in 48 hours? How long are your shifts? What do you do? How does your body handle that?
I steer oil wells to make sure they stay in the correct rocks. When we do operations, I do 12 hour shifts. The chap on nights lost internet. Broadband down, starlink fail and Verizon went down too so he lost all backups and I had to cover. Doesn't happen often. Body handles it as expected. Bad for a couple of days and then a long sleep!
