um just take double the recommended dosage and work ur way up from there. phenobarbitral is a shitty drug anyways, benzos (xanax, valium, ativan, klonopins, ect) are much better!
Well for one barbituates were essentially "replaced" by the benzodizeapines in the 80's. For one b/c barbituate withdrawal can cause death and actually is pretty damn dangerous once u get addicted to them. Benzo's are yes safer and yes benzo's also provide a better "high/feeling"!
