I am on tylenol 3s for my back pain and i came across methadone i wad wondering what would happen after i take it, like the days after taking the methadone will codeine stop working? Will it stop forever or just for a few weeks until my brain washes the tolerance? Please help me.with this because i need the t3s for my back and i am not willing to render them useless just for one fun night. Also, is methadone any good for recreational?
