As many above me, no, benzos are not good for CTB. Benzos however are really good to accompany any other method. E. G. I will use SN method but I'll make damn sure to take a lot of benzos to calm my nervs. I never heard of anyone CTBing with benzos, you would need to take so many tablets that is phisically impossible as you would fall asleep before toxic levels can be swallowed.
