I found you via google.I suffer from kidney failure and am on Dialysis 3 times a week.I'm in the hospital quite a bit,where they always give me dilaudid for the pain.Only 0.5 mg via I.V. What I discovered was that they were throwing half the dosage tube of good dilauded away in those sealed drops in every hospital room.So I bought a 3 foot grabber from home depot and fished all the half tubes out and in a weeks time in the hospital had collected over 20 mg's og liquid dilaudid and was looking for a way to use it.Also came across the same situation with lorazepam I.V..Google is a wonderful thing.LOL
