Shite.....very spun out to find bupe even mentioned. I went from smoking 20mg a day...much stronger than subing it, to c/t and it wasn't a prob. I could still work, just a bit sweaty. I found methadone 50x worse...well maybe 10x worse. Still worse all the same. I found precipitated w/ds going from 120mg done, to bupe within 24hours was better than an entire week of agony. Sure it's hard, but over quick. Then stoped the bupe next dose and cleaned up with no w/ds. Then sadly, back to bupe a month later. Now i'm a codeine man. Codeine w/ds...meh, easy. Even at 1.5g a day dose. I'd say due to potentiators not very addictive. Peace.
