Experience

Primary effects

  • Zopiclone induces a sedated, hazy, and mildly hypnotic state, primarily functioning as a sleep aid.
  • At typical doses, it causes relaxation and a chilled feeling without strong euphoria.

Peak character

  • The peak involves a quasi-dream-like state, slight inebriation, and headiness with a hint of disorientation.
  • Physical clumsiness and difficulty with normal conversation may occur, creating a dazed feeling.

Negatives / side effects

  • High doses risk blacking out.
  • Users may experience a metallic taste in the mouth.
  • The substance can make speech difficult and cause physical clumsiness, potentially betraying intoxication to others.

Aftereffects / comedown

  • Users report good sleep, with a possible foggy feeling the following morning, though generally feeling well.
  • Compared to benzodiazepines, zopiclone may result in a more apparent headspace and slightly more morning-after lag.
