Just in case you are curious, it takes us three to four days to detox a patient
and get him/her back home drug free
and feeling well on Naltrexone therapy (no opiates).
At home, the basic technique is to space out the amount your friend takes on a consistent manner until you take only at night, than half that amount at night, than every other night and then none. I would say he should space out the pills and try to cut down by 5 mg a day.
