For how many weeks were you on the medication? For how long were you in withdrawal? Heroin, hydromorphone, oxycodone, etc the withdrawal lasts 5-7 days. Were you in withdrawal for that long? I guess the point I'm trying to make is that most addicts are on much higher doses for much longer periods of time -- and the withdrawal is insane. Furthermore, there's a big difference between physical and psychological addiction. If there weren't, then everyone who takes prescribed pain meds for any length of time would be "an addict" because they'll experience a degree of withdrawal. If you identify as a drug addict, that's fine (though I certainly hope you aren't one!).
IV Hydromorphone is also, by the way, 5x stronger than IV morphine. Granted, that's a lot, but nowhere near 100x!
