I've tried it recently, the 1mg blotters with the structural formula on one side and fluclotizolam on the other.
1mg is an ok dose for me (I probably have some permatolerance from past use, but haven't taken benzos regularly for a few years so it's not sky high or anything). Haven't taken clonazolam since 2019, but I think it's about twice as strong? Maybe a bit more. And it does last longer.. Never was a big clonazolam fan, always prefered flubromazolam/flualprazolam/flunitrazolam (if we're talking about the very potent ones)... In general I prefer benzos with a r2' F and not a r2' Cl.
The main effects last around 4h for me + a few more hours of residual sedation&anxiolysis.
It hits much faster than clonazolam, I can feel it starting in around 10-15 minutes and by 30-45 min it's pretty much peaked. Clonazolam took at least twice as long for me.
It's pretty warm/fuzzy/euphoric (if you're the kind of person that finds benzos euphoric). It's also pretty hypnotic (not so much that it'll knock you out, but you will feel sleepy) so if your goal is just preventing wds/anxiety it's probably not the best choice.
Imo it's more of a benzo you take if you enjoy benzos and just want a few hours of fun and not so much something you'd take for anxiety.
If you're looking for something to taper with try norflurazepam/flubromazepam (they aren't ideal, because they are a bit too enjoyable.. but they are available at just about any rc vendor) or diclazepam (if you can still find it). And if you are looking for something for daytime anxiety, pyrazolam is very nice.
