I have been taking
Xanax for 4 years and haven't experienced that nor heard of it. It may be a side effect of another medication or another underlying condition/problem. I would definitely mention this to you dr. Also, I'm sure that you are aware that Xanax is extremely addictive. A 0.5mg of Xanax is = to 10mgs of
Valium. Sometimes the "cure" is worse than the disease. FYI...Xanax taken for long periods of time can create insomnia. Take a look at
www.benzo.org.uk/ & click on Ashton Manual. You will get some excellent advise and insight on Xanax & other medications. Please be careful with the Xanax...wish my dr. would have never prescribed it. It has been the worst thing in my life.
Best wishes.
