I was on a morphine pump for 8 days and
then Dilaudid and
morphine pills, tapering down to Percocet 10 mg, Vicodin
10 mg, Darvocet, and then Tylenol #3 for a total of 4 months without stopping at all in between, and I never had a problem at all when I stopped taking them. I stopped them because I didn't need then any more. That was in March 1994. I didn't have a single withdrawal symptom.
