Been reading along with you guys for awhile now, and great discussions! I have been taking dilaudid for back problems and had surgeries for about a year now. I've been injecting my pills 4-6mg at a time probably 6 times a day? Couple weeks ago I tried to quit, ended up in hospital overnight with terrible withdrawals. Last night woke in middle of the night with tremors and chills all the classics~sucked. But had not up and quit? Does anyone know why? Can withdrawal symptoms come on that quickly? I need to get off this NOW! Looking for experienced words of wisdom how I can taper off this without such Horrid side effects!
