Six Years With the Knockout Night Nurse
Citation:   Asante. "Six Years With the Knockout Night Nurse: An Experience with Flubromazolam (exp114825)". Oct 2, 2020.

75 - 500 ug oral Flubromazolam (liquid)
It was in 2014, now 6 years ago, that I acquired Flubromazolam. The moment I saw the molecule I knew I had to have it, the way the molecule is put together just SCREAMS extreme benzodiazepine. Let me break that up for you:

It has the bromine on the primary phenyl group that is associated with hard-knocking analogues as brotizolam and phenazepam. Then, further augmenting the effects, on the secondary phenyl ring there's the fluorine atom that gives rohypnol its enhanced hypnotic punch. It does not stop there because it is a -zolam drug by the added methyltriazole group.

So here you have, basically, something that is very much inbetween Brotizolam, Rohypnol, Triazolam and Midazolam in terms of structure.

I was immediately spellbound and got it from China while the first reports were still coming in. I needed no reports to see this molecule was a bell ringer through and through, you just about cannot structurally emphasize a benzodiazepine more than this one was emphasized.

This proved entirely the case.

On my analytical scale I weighed some milligrams and dissolved them in an equal number of mililiters of pharmaceutical grade propylene glycol, so 1mg/ml.

For the first test I took a then commonly established doss of 0.5ml = 500 micrograms.

What happened! In 10 min I felt it, it got way strong and within the hour a very powerful sedative effect just shoved me into bed, 2 hours early, and I slept for 11 hours, three hours more than usual, still pleasantly intoxicated for a few hour more.

I had ache that comes from having lain completely still for too long.

This was SO STRONG, I wanted nothing of this dose anymore. I had had the most restful sleep ever but this was SO restful I didnt even turn myself as I should've.

The next dose was 0.4ml - 400 micrograms, dosed with a syringe, squirted on the tongue (it tastes foul) and chased with some water. The effect was almost identical.

Blotters nowadays contain 250 micrograms of the stuff.

I tinkered around with the substance and settled around a dosage of approximately 100 micrograms, a standard LSD dose of an RC benzo, or roughly 75-150 micrograms, as my default dosage.

100 micrograms interrupts intense anxiety attacks, sober or drug provoked ones, and typically there's a half hour nap somewhere around 2 hours in.

This stuff, as predicted by the structure activity relationship, is as potent and hypnotic as benzos come.

In oldfashioned mental institutions, think One Flew Over The Cuckoo's Nest and earlier, the night nurse used to have a knockout drug like amylene hydrate, paraldehyde or chloral hydrate to lay out the most stubborn insomniacs. This birthed the phrase "Knockout Night Nurse".

Flubromazolam has earned the nickname "Knockout Night Nurse" with me, JYI-73 doesn't have a nice ring to it, and with "Knockout Night Nurse" you have the expectation of a swift pharmacological brick to the back of the head, which is TOTALLY what flubromazolam is about.

It is incredibly blatant as a sedative, so hypnotic that it just about feels like you took a barbiturate. This is a nonfunctional benzodiazepine, because even in the afternoon on a low dose you might take a nap and if you take a higher dose that "nap" lasts 11 hours.

I want to emphasize that there is a medical case of potentially fatal intoxication on the books of this substance at a dose of just 3mg. If you have no tolerance this hits you like a ton of bricks and benzodiazepine overdose is something that is most likely to happen with one as highly hypnotic and muscle relaxing as this one. The subjective effects are most like a barbiturate, and therefore the risks are likely higher than those of an average benzo as well.

I've used this one, on occasion, for 6 years now. I always go for the 100-150 microgram range now. I would not exceed a quarter milligram, I respect this drug to the moon and back.

With as little I need, as infrequently as I use it, its likely that Chinese gram will last me and my closest ones a lifetime.

How often do I really need to get batted in the back of the head in life? Not much - and that is really all this drug is good for: subduing raging anxiety and panic attacks and nuking the most tenacious insomnias.

Cherry on the cake, it truly lasts 12-20 hours or so, so potent yet so long lived! It puts me to bed and gives a pleasant skew to the first half of the subsequent day.

One MUST liquid dose with this one. The effective dose range is the same as that of LSD and unlike LSD overdoses and drug mixes are not benign. I never once mix this with other depressants or, generally, other drugs period.

Proceed with caution, in the knowledge you're working with the ultimate in sedation that benzodiazepines can offer.
