bandnmom, I'm sorry you decided to stop taking the vicodin since it apparenty helped your pain. You need to understand that there is a big difference between addiction and physical dependence where opiate therapy is concerned. Addiction is a mental illness; physical dependence and tolerance are normal side effects of taking opiates on a regular basis. You will experience withdrawal symptoms if the drug is suddenly discontinued. This is important: experiencing withdrawal does NOT mean you are an addict.
A patient who takes more meds than prescribed, and for reasons other than pain control is going down the road to a true addiction. To make matters even more confusing, some patients exhibit what is called pseudo-addiction behavior. They will doctor shop trying to get pain meds. Does this necessarily mean they are addicts? No. In many of these patients, they are simply dealing with untreated or undertreated pain. When the pain is treated, the behavior stops. An addict won't stop looking for more and more drug sources even if the pain is under control.
It doesn't sound as though you were taking a whole lot of the vicodin. Why not just use it at night so you can get some sleep? I have pretty bad arthritis in my hips, and it's always worse at night - I'll wake up every hour or so, and some nights sleep is impossible. Soaking in a hot bath is about all that helps me when that happens.
