@geezer43 I am 76 with pain from disc herniations and disc degeneration with recent nerve ablation partly helping. I have been taking morphine at night and early morning. During the day I have a regular regime of Tylenol. My husband drives instead of me as my knee joints are wrecked and seize up later waking me in night. I feel shut in and wonder if I drive would any morphine in my bloodstream be risking problems or am I just over cautious.
