I remember hydromorphone withdrawal as a 9-hour downright dissociative and hallucinogenic violent spike of symptoms that had me in post-acute withdrawal by sun-up the next morning . . . Palladone, Hydromorph Contin, Exalgo withdrawal would be Satanic . . . on the other hand, when I was in much worse shape than today and the doctors, board of health, and manufacturers were working together to literally give me a one-twelfth of a kilo morphine base equivalent per month and my main GP shuffled off this mortal coil at the age of 93, probably being a multi-decade morphinist for reasons lost in the mists of history himself, my wiseacre new "specialist" insisted I get off the "shitload of meds" and after a four-hour debate with her said she would put me back on a lower dose afterwards. Well, given that I was also rapidly losing weight and was full of lipid-solubles like hydromorphone and oxymorphone in addition to morphine, the backlog in my body staved off withdrawal to one degree or another for two weeks and by that time I was on an aeroplane back to Austria for good. Arsehole.
It was one of those karma things too -- I found out that the specialist who wanted to go all Clockwork Orange on me narrowly avoided the calaboose for something with stock fraud and the GP I had for those couple of weeks was this very sweet small Russian redheaded lady about 145 cm tall who despite the politics of it really wanted to help and offered to give me some levorphanol. I run into her in Zagreb 18 months later, and two days later meet her for pastries and tea and she jumps my bones later that afternoon. Otherwise I would have had to find a doctor at another office and then wait 731 days after the last appointment.
