I have been on xanex for 9 years ..I take 3-4 mg a day. Because og heavy narcotic use in my area my Dr. decided to giveme a urine test (which is understandable….To my amazement I get a call to come back to the office to discuss the urine test. He told me I have no detection of the benzo in my system what so ever!!! I was floored, how on earth can this be? There is no way sense I take the amount I told you about religiously …He said I was not taking them and the test proves it, “the test don’t lie” as I was told, it made me feel like a drug dealer…The test was examined in a lab….please help if you can , im overly confused!
