i used to take 80 mg oxy's twie daily and it made it possible to perform daily activities such as simple things like doing dishes and now I ant lean over the sink for ten minutes.Doctor started me on 10 mg oxy 3x's daily and im basically couch ridden because dr's are all scared of being sued and they want me to return every two weeks and pay office visits evry time as a cash patient. any advice on dosage issues for heavier people?
