I was switched from Oxy (liquid) to morphine after tongue cancer surgery and months of mouth and neck radiation treatment. Was on a maintenance plus "break through pain" prescription for 6 months. It took a week to get withdrawal symptom free with the first 3 days being the worst. It wasn't terrible but I don't want to have to do it again.
