"great pain narcotic, works in about 20 minutes after oral administration. i am on 4 mg tablets, every six hours, usually one a day does the trick. i also take it in conjuction with 30mg of oxycontin er. i can actually get out of bed and do something. be advised though that withdrwals could be severe. i had withdrawls after last dose twelve hours ago, so you must taper off. do it with your doctors help though."
