I am 52 years old,female,and due to the fact that I suddenly lost my job of 19 years,I went to my family doctor for a prescription for Xanax,due to extreme anxiety attacks.I knew this drug had a rebound effect within a very short time,and I was on it for about 4 and a half weeks.I tried to discontinue it slowly,reducing my dosage over a period of about a week.I should mention that I never,even at the height of my anxiety,took more than 3 of the .5 mg pills in any 24 hour period.My question is,today is the 6th day without any Xanax,and I still am suffering from what I believe to be withdrawal symptoms,such as extreme fatigue,inability to concentrate,dry mouth,the shakes,and occasional severe insomnia.How long should it take before these symptoms go away?
