Try actually reading what I said.
Benzos have various effects, muscle relaxant, anti seizure, calming anxiety, hyponotic, etc. Temazepam is an example of a benzo that is primarily used for its hypnotic effect and not as a tranquilizer for anxiety.
So they do have very similar effects and work in similar ways. So similar in fact that they even have the same antidote in case of overdose. I mean think about it, if they weren't similar why would they use diazepam to taper.....
http://en.wikipedia.org/wiki/ZopicloneZopiclone, a benzodiazepine-like drug was introduced and initially promoted as having less dependence and withdrawal than traditional benzodiazepine drugs. However, zopiclone may have an even greater addictive potential than benzodiazepines and has been described as a "benzodiazepine in disguise".[27][28][29]
I would find a more reputable source than wikipedia but I can't be bothered.
Zopiclone is nasty stuff and best avoided, OP should speak to his doctor.
