With the amount of oxy he was taken sub might not work, the dose can only go so high and then it actually acts as anti-opiate, the oens used in overdoses, whereas
methadone is a full agonist
and you can go higher
and higher whatever you need to make you comfortable
and stable. both give you a mild buzz, and both are complete hell to get off of. sub is just as hard no matter what anyone else says. its just as hard as methadone, its opiate withdrawal times two months. it *****.
