    Summary dose.wiki TripSit PsychonautWiki

    Zopiclone is a non-benzodiazepine hypnotic intended for short-term insomnia treatment (2-4 weeks maximum). It produces significantly more amnesia and disinhibition than benzodiazepines at comparable doses. A characteristic metallic or bitter taste occurs in many users.

    Tolerance

    Build-up develops within 1–2 weeks of nightly use; acts on same GABA-A site as benzodiazepines
    Reset Falls after you stop, at a rate that varies from person to person. If you've been using regularly, cut down gradually with medical help rather than stopping suddenly.

    No tolerance chart. Our decay curves for these drugs were estimates, and a curve can make tolerance look longer-lasting than it is, which is the dangerous direction.

    How fast tolerance to these drugs fades after a break has not been measured well enough to draw, so don't count on a dose you used to take still being safe: after time off, start with a much smaller amount and don't use alone. Mixing sedatives with each other, with alcohol or with opioids sharply raises the risk of a fatal overdose. If you've been using regularly, don't stop suddenly: withdrawal from benzodiazepines, alcohol or GHB/GBL can cause seizures or delirium, so get medical help to cut down gradually.

    Effects Erowid

    Aggregated from 23 single-substance Erowid experience reports; 21 Erowid reports where another drug was taken too are left out

    Each bar shows the share of analyzed reports whose text mentions that effect — a mention is not always a first-hand experience (fear of an effect or something witnessed can count). Mentions saying the effect did not happen are left out; that check reads keywords, so it can miss some. The shaded band on a bar, and the small range after its number, is the 95% interval: where the share could plausibly be with other reports of the same kind. Fewer reports, wider band. Tap or hover any number for details. The second value is the Bluelight extractor's per-effect confidence; a dash means the row is Erowid-derived, which has no confidence measurement.

    Also reported in combinations. In the 21 Zopiclone reports where another drug was taken too, 2 (9.5%) mention hospital, emergency services or an overdose, 0 (0.0%) a seizure and 3 (14.3%) psychosis. In the 23 single-substance reports: 4.3%, 0.0% and 0.0%. These are not in the figures above: they cannot be put down to Zopiclone alone, and a mention is not always something that happened to the writer.

    I am a 34yo male, reformed alcoholic/drug user, however have the occasional play around with pills etc. I have not consumed alcohol for 4 years and have been away from street drugs + pot for even longer. I had a rather large cache of these pills (Zopiclone aka Imovane) and experimented over a couple of months.

    I should be dead. If things happened the way I think they did, I should be dead. But one of the effects of Imovane is loss of memory, so I am piecing together my story after the fact. I am a chronic insomniac. I can never get to sleep without the aid of some medication.

    So there was no innate decision to trip on this faithful night, in fact, I had just received my 3 month script off zoppys (15mg per night), and after acquiring said tablets ventured home (the short way) to immerse myself in some gaba-loving.
