Clonazepam is a good long-acting anxiolytic benzo. I find it isn't very sedating once fully kicked in compared to other benzos, infact I don't find it sedating at all (unless a high dose is taken). I'm scripted 2x 2mg tabs each day and find it's anxiolytic, muscle relaxant and calming effects combined with the long duration very good if you're scripted benzos for anxiety. While its half-life isn't as long as diazepam, its effects 'feel' like they last longer.
My tolerance was quite high when I first tried clonazepam but find it a great benzo therapeutically and mildly recreational in high doses. An equal dose of alprazolam or temazepam would be more recreational for example though, imo.
Have little experience with bromazepam, but remember it being an alright benzo. Needed to try it in varying doses to know if it would be more recreational than clonazepam. If you want to not be under the influence of benzos for too long, I'd go with the bromazepam probably, like if you needed to get up early. Have never tried etizolam either.
