how do you guys get drunk consistently?

i usually drink from the bottle so i don’t track how much i drink more just visualizing it/guessing. i don’t know if yall try to stay consistent whenever you drink or have a plan because sometimes i sober up too fast cause i don’t drink enough since i assume ive drank enough when i actaully didn’t. or i just blackout. only one or the other, so do you guys use shot glasses and track how much your drink? or eyeball it? do you guys even have consistency? and do you have a technique? i can never gauge how much/when to drink more/enough.
