Drug effect/experience question - from one that doesnt take drugs

[Captain_Dickärd]

As a connoisseur researcher of narcotics, I've a bit of experience that may be relevant to your questions.

"The effect of the drug also cannot be reproduced by any known drug" This makes it harder to speculate, so take all I say with a grain of sal.

How would you feel time slowing down?

The slowdown effect described is something I've heard a lot. It is described as time feeling as if it were passing very slowly, (minutes feeling like hours) in an extreme case I found someone who had believed they outlived all of humanity because they were convinced they had been sitting in their chair for millions of years. Very rarely heard someone describe the world as moving in slow motion, however.

When you increase in brain activity does that mean you can think clearer for a time?
dont take drugs

With this drug, the increase in brain activity may come from the hallucinogenic effects. This might not help your concentration. Someone tolerant of the drug might be able to focus through the hallucinations, or receive them less intensely.

How do hallucinations work?
dont take drugs

It varies greatly with the drug and potency:

Could be something simple, like seeing the walls "breathe" or odd patterns. Or it could be an extremely intense alteration of your consciousness that defies any description fathomable. Given one of the descriptions for the effect is "spiritual" this may be some potent stuff.

and finally: Depending on how much you take, would you then experience the initial high longer and then hit the deep sleep part later?
dont take drugs

It says the mixture of the drug includes a "complex combination of flunitrazepam, psilocybin".
Flunitrazepam: This is a benzodiazepine, most of them are for sleep-inducing, anti-anxiety, anticonvulsant, and muscle relaxant purposes. It also can have paradoxical effects.
Psilocybin: This alters your perception of time, among many other things. I don't know anyone that can sleep after using this substance. It can cause peaceful feelings of oneness or terrifying feelings. It intensifies what's already in the person in many cases.

It might be hard to go to sleep if you had just taken this stuff. Taking more might make the effect more intense but perhaps not longer lasting; hard to say with a fictional drug. If you kept taking it to beat the crash you would likely pass out in between doses and have a dreamless sleep.
