Hi! In my opinion,neither is true. Are you working a program? Are you ready to quit?
You need to get with your Sub doctor on this. Sub should be tapered slowly,over time.
Do your research on tapering Sub. A taper can go pretty well until you get down to small amounts. You will have withdrawals. The severity is directly proportionate to the drug you WERE taking,the amount, and length of time. If you taper very slowly to tiny amounts of Sub it may go much better for you. Talk to the doctor.
Good luck!
