I agree with Paxiled. Remember, that we have underlying issues for our anxiety and unless we have gained the long term knowledge to confront it and deal with it, this cycle can really take control of our lives. Also, do not come off of the medication on your own...good luck and keep us posted!
The question is, have you fixed whatever drove you to the medication in the first place? That means therapy, usually. And is the medication working? If you believe you no longer need medication, arrange with your psychiatrist (if you have one) to taper you slowly off the drug, as quitting abruptly can cause problems. But if you still need it, then it's not time to quit yet.
