I've actually been doin pretty well with loperamide. I stopped taking such rediculous doses. Nowadays I use it like suboxone/bupe. It def has blocking effects, so it keeps me well and if I dosed in the morning, there's no point to copping dope that day. The doses I use are usually about 50mg or 25 pills of generic loperamide. Recently, I started doing 40mg, in the hopes of tapering off. But then I copped dope again.
I also always use a stool softener with every dose, and that takes care of that department.
The only downside is that this "get out of jail" free card still leaves me dependent on something to fill those opiate receptors.
