I have had negative results for benzos even though I take 5-10mg of valium every day or almost every day. Maybe like mentioned, a blood test would be more accurate. There has to be some sort of level reached before certain meds will show up in a urine test. If you arent taking it daily maybe it wouldnt show, but I cant understand why they wouldnt represcribed because of a negative result, at least it shows you are not abusing it or do they suspect you of selling it? Just curious, you dont have to answer.
Be kind, everyone is fighting their own battles
