I started out taking Xanax 0.25 mg nightly only as a sleep aid, as my eyes felt like sandpaper and were interfering with my sleep. After only a few weeks, I began to experience severe anxiety during the day, which required more Xanax (up to 1 mg per day). I began to think that I was going crazy. I also developed a tremor and underwent an extensive neurologic evaluation, including a lumbar puncture that resulted in a severe spinal headache and an ER visit for a blood patch to stop the leaking cerebrospinal fluid. Xanax was never suggested as a cause for my tremor, although my dose relieved the symptoms of the tremor. It got to the point where I needed to dose every 6 hours as the Xanax would only last a few hours, then I would experience severe symptoms like difficulty breathing, chest tightness, and inability to swallow. I lost about 15 pounds (I am only 5’3” and got down to 115 pounds). I looked like a skeleton. I was terrified to be alone. I would wake up at night after 3 hours of sleep with my heart pounding and in a sheer panic. After doing my own research, I discovered that I was experiencing inter-dose withdrawals and had become dependent on Xanax. - www.benzoinfo.com
