When you are using a lot of energy and feel like you should be moving fast, but you're still moving slow.

When you feel like you are expending a lot of energy and should be going fast, but you are still moving slowly.

A condition when you take something intended to wake you up (caffeine, energy drink, etc) at the same time you take something intended to calm you down or put you to sleep (adderall, sleeping pills).

Your body ends up feeling very sleepy/sluggish while your mind is usually racing and awake. Not a fun experience.
