Well I do know for a fact that both Fentanyl and Dilaudid have very short half lives, fentanyl
in particular. The only thing about fentanyl
is apparantly the gel
from the patch can stay under your skin and continue to release for a few days even after the patch is removed. Dilaudid half life is about 5hrs and from what ive read fentanyl is even shorter, perhaps 1-3hrs.
But I dont know. I woke up today, 2hrs past 3.5 days and I still feel relatively normal.
