I think a lot of people don't really know the difference between benzos and Z- drugs, so we don't really know what the prescription was for. Also, many countries have decided that the research hasn't shown any reason to prefer Z- drugs like zopiclone over benzos for short-term use.
I took one, one night when I felt particularly hopeless. But I might just do the rest every night in a row to do that reset. In my mind I don’t want to “waste” them as it feels somehow safe to have them in my drawer just in case. It’s Temazepam btw.
