Not yet investigated
What we have so far
It shortens the time to fall asleep and then suppresses REM and fragments the second half of the night. Sedation and sleep are measurably not the same thing.
This star is on the map because the show intends to take the question apart properly — the trials, how it is actually tested, whether the thing sold is the thing studied. That work is not done yet, and nothing here should be read as a conclusion. When the investigation is published it will appear on this page.
