well a lot of benzos, even though they make you pass out,seem to alter your REM sleep so even if they help you fall asleep they aren't necessarily helping you get better sleep, besides temazapam being the exception I believe. not advising it here but if you really want something to knock you out , Benzo wise, phenazepam, no benzo in no amount have ever kept me asleep longer than 10-12 hours. once I took about 10 mg (also not advisable whatsoever I have a formidable tolerance, but even for my tolerance it was reckless) and literally slept for 48 hours straight with the except of a couple pisses and probably a quick joint or two. seriously, I was alseep all weekend. but a way easier and better get way together some sleep in phenibut. not a benzo or even illegal but a gabapentinoid. I dont think a chemical compound have given me such good sleep consistantly as phenibut. its not sold in the US but its not considered a drug, but a nutropic. you can order it offline. downside is its not advisable to use once a week, it has anxiety effects like benzos that can be quite powerful. it is addictive if used recreationally. fair wairing. best of luck
