It will only continue to work if you let your tolerance reset. Imo try to use alprazolam at most 3 times out of 7 days, when you most need it, and pop it off by the box (the way bars break into quarters), take whatever the smallest interval is that you can break your pill into. Start at 0.25mg of alprazolam (aka 250 micrograms, often written as ug), wait 45-60 minutes, and reflect if you need more. Exceeding 1-1.25mg without tolerance is unwise in my opinion, and preferably you keep your tolerance next-to-nothing by not overusing alprazolam.
