Hey everyone I have been searching online with my question and cannot seem to find a straight answer. I go to a methadone clinic every week and I am 2 yrs and 6 months clean of opiates. I have crazy insomia. I have a few ambien 5 mg and was wondering ho long ambien stays in your system and also if it would show up on a drug test that the methadone clinic does on me. Please help. I have been taking unisom the past few months and that doesnt do much for me.
