How are you actually measuring 'sleep quality' when you evaluate anything?

Something that bugs me in a lot of sleep threads: people say 'my sleep quality improved' but rarely say what they mean. So I wanted to open a methods discussion — how do you separate a real change from a good week or a placebo bump?

For me the useful distinctions have been: total time asleep vs. how rested I feel, number of awakenings, and morning grogginess, which don't always move together. Wearable 'deep sleep' numbers I take with a big grain of salt — consumer devices estimate sleep stages and can be pretty off compared to actual polysomnography.

I'm deliberately not tying this to any specific compound because the measurement problem exists regardless of what you're evaluating. If you can't measure it reliably you can't attribute a change to anything.

What's worked for you for keeping yourself honest? Sleep diaries, subjective 1–10 ratings, something else?

A boring paper sleep diary has been more useful for me than any gadget. Writing down bedtime, rough wake-ups, and a morning 1–10 catches patterns the wearable's pretty graphs actually obscure.

The deep-sleep estimate point is huge. I stopped chasing that number once I read how loosely consumer wearables map to real sleep staging.

Strong topic. The single biggest honesty tool is a pre-registered expectation: decide what you'd count as success and over what window *before* you start, so you're not retrofitting the story afterward.

Also worth building in a wash-out and ideally not changing anything else concurrently. Most forum 'it worked' reports fail on exactly those two points — not because people are dishonest, but because unblinded self-tracking is genuinely hard.
