I've been on xanax around a month or so...5 mg 3 x's a day..at first it seemed to make almost all symptoms go away..now the effectiveness is wearing off building a tolerance to it..so when it gets close to time to take, i notice symptoms a little worse..how much are you on? i am trying cymbalta an anti-anxiety med and also used to treat diabetic peripherial nueropathy (?)..I only had very little twitching..dr put me on xanax 5 months ago..thought all the twitching was from withdrawl..never stopped..don't know..will we ever know? does anyone else build a resistance to xanax? i was told not to increase dosage or times this runs into becoming addicted to it..this stuff is still very scarey..
