Glad to hear you're making progress - it's not an easy thing to do on your own, and UK docs are pretty fucking useless, for the most part. I knew one addiction specialist shrink who I actually respected - he'd done his share of drugs in his youth, never looked down on addicts, and believes, passionately, in harm minimisation, maintenance and tapers. But with the way things are going under the current government - restricting methadone, refusing to prescribe subs for cold financial reasons, telling benzo addicts to fuck off and 'get them on the street', et cetera - he threw up his arms in disgust and decided to change careers.
But like I posted last week you're on a low enough dose that maintenance would be a bad idea, unless you can find a doc (there are some) who'd prescribe dihydrocodeine for a taper. It's not that hard to get hold of, anyway, if you take a look around that there interweb thingy the kids love, but there's obviously a risk involved. Time-release dhc tablets would probably be ideal, as a step down, but though some European countries use them as a methadone alternative, even for H-using needle freaks, that hasn't really taken off as a therapy here.
I don't think it's breaking sourcing rules to point out that codeine linctus is available at pharmacist's discretion in the UK as a cough linctus: very few chemists will sell it in shops, but the interweb's a different story. Half a 200ml bottle's roughly equivalent to 30 mgs of morph, so it can be useful as you titrate down your dose. Only drawback is that codeine has a shorter half-life, though first generation antihistamines like diphenhydramine and promethazine keep it active for a while longer. The linctus might be useful when you get your dose a little lower, and it has the advantage of being both legal and dirt cheap. But I honestly wouldn't bother even trying to buy it over the counter - unless you're a sixty-ish woman with a hacking cough, hardly any pharmacists will sell it. Not that I've ever asked: I blush easily, and the thought of some smug chemist turning suspicious eyes on me and thinking 'junkie scum' is too embarassing to bother with.
If you have money to burn, I'd give serious thought to the Kratom option - there's lots of garbage on the market, but good premium bali can ease withdrawal to a surprising extent, and it's easy to taper down doses. But unless you have a very strong stomach, it generally requires a capsule-filling gizmo to use effectively: it's the second foulest-tasting substance I've encountered, after San Pedro cactus, and with any kind of opiate tolerance, you need piles of the stuff to get an effect, since the stronger extracts vanished. Maybe order a small batch and see if it works for you - they prescribe it as a kind of 'herbal methadone' to H and opium addicts in some Southeast Asian countries, though it's otherwise illegal in the region.
Final thing: loperamide takes 2-3 hours to take effect, so if you go down that route, dose say 17-20 hours after your last bit of morph. It's difficult to suggest dosages, but maybe start with 10mgs or so, and see how much relief it brings. It's pretty damn good at suppressing withdrawal symptoms, but it seems, from the many heated loperamide threads on these forums, that very few people experience any kind of pleasurable or painkilling effect from it, even at massive doses, so it doesn't help with the psychological aspect of addiction or cravings. And it can cause pretty nasty nausea, so start small and see if it works for you.
Anyway, I've said it before, so I'll say it again: good luck, you're doing well. Better than me: I fucked up my benzo taper and have been indulging in morph, codeine and dhc all week, after discovering a forgotten stash (shows how out of it I was last year, before I tapered: I've hardly ever lost and found drugs in a 25-year career of abuse. So I'll probably be reaching for the loperamide myself tomorrow. Luckily, I brought a shitload over from the US last year, and it should see me through the after effects of a mild week-long binge. Forgive the babbling: I finished off my dhc this morning. Barely touched the stuff for a year, but my tolerance doesn't seem to have gone down at all. It's funny - I chipped H on and off in my late teens and a few times since, but never found it that compelling, so it was easy to avoid daily use and addiction. It's the milder opiates that sank their teeth into me, and I suspect I'll always go back to them now and again. Better than sex - well, most sex, in my experience - and every bit as problematic in the aftermath.
