Fade in.
Close-up on a hand, shaking slightly as it lifts a metal cup. Pan as the camera moves to the subject's face, barely able to take a swallow of fluid without spilling it. After a half-coughed swallow, the hand half-slams the cup back on the workspace. The man shakes his head, unable to concentrate, pushes off from the workspace, and snaps at several other people as he walks briskly away.
From the second I saw the hand shake, I thought, "He's low. He's acting like he's low. Get the man some orange juice; he's about to pass out."
