Norflurazepam is a decent benzo .It is a metabolite of many benzos, even midazolam, which is in a different family of benzos (Imidazobenzodiazepines). I think that flutoprazepam and flurazepam are superior to norflurazepam. Although norflurazepam is more potent by weight than flurazeapm, fluraz has a more rapid onset, and it has a nice kick on the come-up. Flutoprazepam is much more potent, and is quite the heavy-duty hypnotic.Hangover is heavy. It is long-acting, and I think it's one of the best for use is to potentiate opioids and to put the brakes on an amphetamines or cocaine crash. Norflurazepam plays a role, but other metabolites of fluto do more.
