Background Well, I am almost 19 years old and have more psychoactive experience than most. I have tried over forty five psychoactive substances and hope to find many more. Benzodiazepines are a new interest of mine.

Summary
Flurazepam is a long-acting benzodiazepine hypnotic prescribed for insomnia. Its active metabolite N-desalkylflurazepam has an exceptionally long half-life (40-250 hours), causing next-day sedation, cognitive impairment, and increased fall risk, especially in elderly users. Tolerance develops within 2-4 weeks of regular use.

Description
Flurazepam Source: SubstanceSearch (substancesearch.com) Oral dose (mg): light 5-10 · common 15-30 · strong 30-60 · heavy 60+ Oral duration: onset 15-45m · come-up 0.5-1h · peak 1-2h · offset 8-12h · total 12-16h · after-effects 24-48h Note: ranges are harm-reduction guidance, not a prescription. Start low, go slow, and test your substances.
Tip: for quicker logging you can also add a Custom Unit in the app, e.g. common dose ~ 22.5 mg (Oral).
The app keeps custom substances simple, so the full dose ranges live in the description text above. Ranges are harm-reduction guidance, not a prescription.
Tolerance
Build-up
develops over 1–4 weeks of daily use; hypnotic tolerance faster than anxiolytic tolerance
Reset
weeks to months depending on half-life and duration of use; taper recommended
Tolerance Decay
Half tolerance
14d
Baseline
~60d
Empirically, hypnotic tolerance commonly emerges within weeks, with partial reversal over several weeks after cessation; cross‑tolerance occurs across GABA‑A benzodiazepine-site agonists (e.g., other benzodiazepines, Z‑drugs).

[Erowid Note: The dose described in this report is very high, potentially beyond Erowid's 'heavy' range, and could pose serious health risks or result in unwanted, extreme effects. Sometimes extremely high doses reported are errors rather than actual doses used.] Dalmane Flaurazepam I have a chronic sleep disorder.
Flurazepam (aka dalmane) is a good chill pill, but is not of great recreational use. It takes about 15minutes to a half hour to finnaly kick in, once it does it feels pretty neat. I only take a low dose, and I'm not sure what would happen at a higher dose then 15 or 30mg.
I rapidly develop tolerance to sedative-hypnotics. My physician and I were troubled when all the traditional sleep aids had failed: Ambien (zolpidem), ProSom (estazolam), Valium (diazepam), Restoril (temazepam), Atarax (hydroxyzine).... I could go on.
Brief history: I have been battle depression and drug addiction. The usual. Diagnosed bi-polar/schizo I had been on every antidepressant under the sun, abilify, olanzipine, geodon, seroquel XR, zoloft, you name it, they were trying it.
I have taken flurazepam on multiple occasions, one thing they all had in common was the drug left a nasty taste in my mouth for a day after taking it. It was the least euphoric and the worst curer of anxiety of all the benzos I've taken.
Flurazepam first time This is my first experience with flurazeapam. The first thing i did was open the 30mg capsule and try snorting a little. Don't do this it's not good, like snorting soma. I put the rest of the powder on my tonge and swollowed it with some soda. The high hit me pretty fast.

This was probably my third time taking Flurazepam via IV. I like it,it's not bad. There is no rush really..and it is only a partial agonist but that's another thing I like about it.
