>the effect of poor sleep seems to be MUCH worse for me than other people. I go from extreme motor coordination to dropping cups in a span of 3 days of poor sleep.

Are you sleeping enough? When I was getting too little sleep, averaging 5.5 hours per night, this described me well. A single sleep interruption could make me lose most of a day of work. I'm sleeping better and longer now, and it seems I'm more able to tolerate small interruptions.

Yeah I’ve gotten 8 hours of sleep almost everyday for 15 years, ever since I put 2+2 together. In my early 20s, I didn’t like being bad at sports and I found sleep was my single most important factor.

Similar to you, I also noticed that if I miss good sleep for several days, it stacks. I treat sleep like a battery. A day uses up 20% and good sleep fills it back up, but only like 30%. One missed night isn’t that bad but I also can’t recover several nights’ worth.
