My doctor prescribed Xanax 8 years ago for sleep after my sister died very suddenly. I have taken .25 mg as needed ever since, mostly for sleep help but sometimes for anxiety and/or panic. I don't take it often, and 20 pills usually lasts me for several months. I have never felt addicted or suffered any negative consequences from taking it occasionally, but now after reading comments on this forum, I am feeling anxious about taking it.
