I bought a fair amount of it online last year from Russia/Eastern Europe, because it seemed like it had limited use during withdrawal but mainly because I remember reading some things suggesting that a fairly constant regiment of it after kicking could reduce opiate cravings (not just alcohol cravings, which it was most famous for, because of that book "My Way Out" by a French doctor in NYC (Amiesen?) about how he quit booze with baclofen).
I haven't tried it yet, but if/when I finally get off opiates, I think I'll try it as a "maintenance" type thing. This might be the perfect time for you to experiment with it, Chip. Look around online for some affordable sources -- Lioresal is the name it's known under in India, generally, IIRC. I can also go through my browsing from last year and try to find where I bought it, I think I got most of it from a Bulgarian site. It wasn't very expensive (and it's not a controlled substance in the US, although it is Rx-only), but it wasn't dirt-cheap either -- I still had some money to play around with on experiments back then.
EDIT: Here's the article on baclofen for opiate dependence:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC293465/ Mainly I'm interested in the potential to help PAWS. 12 weeks post-detox, "Treatment retention was significantly higher in the baclofen group" and "Baclofen also showed a significant superiority over placebo in terms of opiate withdrawal syndrome and depressive symptoms. Non-significant, but generally favorable responses were seen in the baclofen group with other outcome measures including intensity of opioid craving and self-reported opioid and alcohol use."
But the kicker is that the baclofen-takers still ended up using just the same as the placebo: "However, no significant difference was seen in the rates of opioid-positive urine tests. Additionally, the drug side effects of the two groups were not significantly different."
