Well, I've finally ordered:
40 x 60mg pure Codeine
30 x 2mg Subutex
20 x 100mg Tramadol
I've also decided to stop taking the paroxitine. I have previous experience with this SSRI and personally don't mind the withdrawal effects... I'm either tough or brain-dead!

I don't even need to taper off it. I just "suffer" the zaps for a week then it's over. Then I'll be able to enjoy the Tramadol a bit more!
So, am I right in thinking?:
Tramadol + Subutex = OK
Tramadol + Codeine = OK
Subutex + Codeine = NOT OK (or rather, pointless, as Subutex will stop the effects of Codeine)
And, if I'm going to enjoy these relatively mild opiates without the certainty of addiction (accepting that there is always a chance) can anyone give me some advice about frequency/amounts of ingestion?
