Depends on the doctor, some of them are pretty crazy and will put you on a 16mg per day dose if you have a large heroin(or other full opiod agonist) habit, which i believe is ridiculous. buprenorphine is a very potent opiate considering its binding properties, so as soon as you feel dopesick, 4-6mg should get you feeling ok. id suggest staying on that dose for 1 week, then reducing your daily dose by 1 mg per week. consult a reputable pain management specialist before doing anything. some docs are quacks and will lead you astray(to line their pockets), but you may have other issues that im not aware of which could influence the dosage.
