Off days suck. (ADHD, mh-)
me, sitting at computer: "I want to do a thing."
ADHD brain: "Nope! Tired, don't wanna focus, can't possibly do the thing."
me: "Fine, I'll go get a nap." *lies down*
body: *too awake to rest*
me: *stands up to head back to computer*
brain and body in collusion: "Yeah, let's stare aimlessly at a bright rectangle and yawn a lot!"
Fortunately, this only tends to happen on the one day a week I don't take my Adderall. Still, it's so thoroughly frustrating....
