I have been addicted to opiates for most of my life. The past four years I have been on methadone and let me tell you, it has literally saved my life. I no longer use heroin and have been able to get and keep a well paying job. The biggest problem in my life right now is chronic insomnia. The clinic where I recieve my methadone does bi-weekly urine tests for illicit substances. The only medication I take other than the methadone is Benadryl (diphenhydramine) to help with sleep. I have tried other sleep meds but the side affects were intolerable. My problem is that my urine tox screens keep coming up positive for benzodiazipines when I take the Benadrly to help me sleep. Nobody can figure out why this is happening and I am very close to being kicked off the clinic due to the positive urine drug screens. Any information will be greatly appreciated.
