Am I doing something wrong? I’m still sleepy even after 8 hours of sleep.

I’ve been working from home for about two years now and I’m still struggling with sleep. I always make sure to get 8 hours of sleep but by work, I’m fighting to keep my eyes open. I’ve tried coffee (to which I am immune now), short walks, even bought a standing desk and cold showers but nothing really works.

I don’t really think it’s the work itself, I like my job but it’s like my body just lacks rest or I don’t get that real sleep other people were mentioning on other posts I’ve read.

What did you do to actually stay “alive” during work? Do you schedule a break at a specific time? Is what’s happening even normal? I’m just actually tired of fighting sleep every time.
