It is also a constantly moving goalpost that our body never quite figures out. Some days 7 hours of sleep is fine, others you need 10, and your body is really bad at telling you which days need certain amounts of rest.
yeah but how do i get out of bed when it physically hurts to even think about moving my pinky finger in the morning? i have to sleep like 10 hours for that to go away.
have had bloodwork and basic heart/breath check done as part of another investigation and i'm like exactly in the middle of the range of healthy values.
i guess i'll have to try forcing myself to do that, problem is that it takes me hours for the bone-deep lethargy to bleed away, and before that i can only just about haul myself into my computer chair
