It's the Br innit I think. I do not fell any other benzo like effects from the low dose but as I was opining to another the Br doesn't seem to adhere to the rules of tolerance. Just my experience. That muscle relaxation and whatever else it causes works every time.
Um... I find what I have stronger than alprazolam and lasts longer like valium. It kinda feels like a quick hitting high dose valium to me. I don't black out. I will
pass out.
Man I have abused the shit outta every drug I have ever had my hands on. I know how this substance can get outta hand and it ain't never perty. No jail just banged up from falling around. So I keep it low for more than one reason, really. Sustainability and if something goes sideways and it's gone the WDs won't be shit.

Been there with high dosing and sudden cessation and it's spooky in the least. Maddening.
Decades of it...
