I maintained a ton of muscle that I had from when I was serious about bodybuilding and I still enjoy it as a hobby to this day but had to stop a few months ago due to serious addiction getting out of control and basically took over my life. But even when I was just using hydromorphone IV and nothing rlse , it was heavy use daily, I maintained an above average physique and maintained majority of my muscle from my sober days simply because I was eating enough and I guess the right things wasn't too much of a junk food eater back then. So to my surprise I was able to stay above 200lb while lean from eating and that was it eventually I had stopped lifting because I figured what's the point if i was still in addiction no longer able to make progress. But when crack introduced itself and gripped my very soul that's when I lost the gains, had basically stopped eating almost completely and dropped from 205-210ish lean to I'm guessing 185-190 even leaner but weak looking. Hope this info helps answer your question.
