I don't mind the itches shambles, but it can go too far, I have a scar on the top of my foot thanks to opiates.
I second (and third, fourth, fifth and probably quite a bit further) you on the J collis browne's mixture, I still haven't got over the fact its OTC, and nearly everywhere seems to stock it, the ones that don't, generally don't have anything worth shitting on (or being constipated and squatting pointlessly over) to speak of, unless its those crappy pharmacies that get saved as a source of promethazine whilst doing the rounds.
It pisses me off though that they can/will only sell one bottle of anything worth having in one transaction, and when you have bright red hair, and are rarely seen outside a leather trenchcoat, newrocks and wraparound shades, those fucking pharmacists recognise you easily.
There are another couple of OTCs worth having in my experience with them, pulmo bailly cough mixture, which tastes absofuckinglutely awful, I think its something like 70-ish mg of guiacol and 7mg codeine/5ml, comes in 100ml bottles, really truly disgusting stuff but drinkable, couple of bottles of that is half decent, or handy enough to attempt to saturate the shite outa CYO-p450-3A4/2D6 before cracking open the gee's or J.collis brown's mixture though.
Gees linctus pastilles....hehe now if there was ever candy made for BLers, they, are it

Exactly what it says on the packet and tasty enough to eat by the bagfull, makes me wish they could sell those in ye olde style sweet shops, where everything comes out of those square jars and is measured by the quarter lb...
The other is terpin and codeine linctus, has a little (but not much) more codeine than bog standard linctus, but its full of fucking pine turpentine, and tastes like it too.
I ran into something else lately too, although I can't for the life of me remember what it was, but what surprised me was it had both CCl3 and EtOEt in there, enough to pong like shit of ether, and taste like it too...wish I could remember what the damn brand name was now :/
IMO any of those tablets aren't worth bothering with, TBH they don't even help me with pain that much (or didn't, before I built up a tolerance....damnation why did I ever have to go and get glass through my kneecap and need opiates, far better when one doesn't need them IMO)
