Most I ever took was 60mg within the space of like 8 hours. Though you can't technically die from benzo overdose alone, once from taking 20mg of xanax all at once I passed out on the road right infront of an oncoming transport truck... It is extremely to die from doing reckless things you will not even think about while on it. Benzos are more bingy and fiendy than any other drug once your on them, as once you feel the buzz there's no stopping you from popping more and more. Honestly the best bet for if you wanna have a semi blackout without getting yourself into a disastrous situation that all benzo lovers get themselves into, is to have your dose on you and have a friend hide the rest of your stash somewhere in your house and not tell you till you're sober.
