A friend of mine has been on 24mg daily of suboxone for 3 years is determined to see if they can even feel high again? How long and how many Oxy80s would it take for this person who is HUGE (6'5 and well over 300lbs) to feel a high again? How long after the last suboxone would they have to wait and how many 80s would it take? After 3 years of the highest sub dose allowed they are convinced it would take at least 400mg of oxy to even sort of move them. Thoughts and advice welcome.
