If you’re going to do a slow taper then you wouldn’t want to decrease your dose by a whole pill, it might cause you a very rough time when the withdrawal sets in. I tried to decrease my dose by half a pill, 0.5mg. and after a week or so I started feeling very sick but that’s me, perhaps your experience will be more tolerable, either way you should be doing this with the help of a doctor who is experienced with benzodiazepines, best wishes.
