I have been taking low dose Vicodin for a couple years (1-2 per day on and off) for back pain. I'm not addicted since a have no desire for it and actually can't remember the day last week that i stopped. But,I was obviously was physically dependent since I am having classic withdrawal symptoms. It has been 6 days from my first symptom to now. Nausea, loose stool, light headed, etc. Can you tell me how long the symptoms usually last.? And, if I needed to relieve pain in the future, what is the likelihood that even for a short period I would have withdrawal symptoms? Thank you
