I have been taking Vicodin as prescribed (or a little more), about 8-10 tabs of 5/500 per day, for four months now, following reconstructive surgery with complications. I admit my pain isn't as great anymore but I still want the pills. My question is just how long does one take this med before it's a serious problem resulting in difficult withdrawals, etc? I've heard of people taking it for years. What is "long-term" use, as far as lenth of time used?
