Since I started prozac 5 weeks ago I have been taking .25 mg xanax in the evenings. Before I started the prozac I was taking it as needed (which was not every day, but I was taking it more and more than I used to). I think I want to quit taking it in the evenings now and only take it as needed. I am afraid to stop though because I don't know if taking it for that long will cause withdrawals and more anxiety. SHould I just stop taking it and take it only as needed? Or should I try to taper somehow. I think it will be hard to taper with such a low dose. Thanks for any suggestions.
