There are sites where you can buy research chem benzos. But they're hell to get off of. Clonazalam was one that would give you the KO punch for a good 8 hours. But when you detox from them, the anxiety, and body aches were awful alone. Add on top of that seeing bright lights in your eyes, when the room is pitch black and not being able to control the muscles in your hand to grab something off the table. Diclazepam would also help put you to sleep, but without the "euphoria" feeling xanax will give you. It's also highly addictive and you have to slowly taper off them once you get hooked.
