I've been taking Zopiclone on and off for years. I'm a shift worker and I use it when required. There was a particular time in my life where I took it every night for months on end. I've taken it with a finger or two of whisky. Not for the lucid feeling it provided, but because I usually have my whisky at night.
Every once in a while, I will wake up in a bit of a mild funk if I wake up within 8 hours of taking the pill.
I take it maybe once a month now. When I do, I sometimes black out and have conversations with my wife that I don't remember. I do not have this issue even when extremely intoxicated. My dose varies between 3.75 mg and 7.5mg depending on how important my sleep is that night.
Overall, the drug has improved the quality of my life and I always have a bottle on standby.
