I have been taking Lorazapam,1mg every night for the last two years. My primary care doctor agrees that if it helps, to stay on it. Without it, I don't sleep well at night. I refused sleeping pills, I don't know if it is addiction but I can't sleep through the night without Lorazapam. If I wake up during the night, without taking the Lorazapam before bed, I am awake the rest of the night. I have had two back fusions so it is not just prescribed for the TMJD. If it is a choice between being addicted and being in pain, I will take being addicted.
Take care and hope things get better.
