The first few years I had RSD I took Vicodine as needed and was not dependent on it. It wasn't strong enough to help that much in the dosage prescribed, so I didn't need to ever worry about withdrawals.

I'm now on much stronger dosages of opiates and I am dependent. When I've had issues getting my meds filled, and started experiencing withdrawals, I fealty with spread beginning in new areas. SO NOT FUN.

You may or may not be dependent. You'll feel it once you start to withdraw if you are, and then you just need to reduce more slowly. A runny nose is often my first clue...
