If this site has a quiet obsession, it is sleep. Not because sleep explains everything — that would be another false binary — but because it is a confounder people are routinely invited to forget.

Stimulant medicines commonly delay sleep. Antidepressant changes can fragment it or deepen it. Discontinuation can produce vivid dreams, insomnia, or exhaustion. Anxiety rises when sleep falls. Activation is harder to interpret in a person who has slept five hours for ten nights.

  • When something significant happens, look at the sleep of the preceding fortnight before leaping to a medicine name.
