Slowly, best w/ Dr.
Best to have a Dr guide you.
But if you must wean yourself alone, your dose (daily?) is quite low, so it should be relatively easy - but still go slowly. It has a long half-life (12-24hrs) so you could do a week or two of every other day, then a week or two of 10mg/day, then 10mg every other, then every 3rd day, 4th day, till it feels ok to stop. Again, a Dr's help is good to have. Best!
