Do antipsychotics and benzodiazepines cause permanent damage, I took them for about 3.5 years and then stopped after reading all of the horrible things about them. I am trying to get off the last pill, lorazepam, I was on 2 mg but a Dr. is helping me to try and get off it, I am down to 1.5 mg and slowly tapering down. Will I get back my natural sleep back once I am totally off of lorazepam? Or will I have troubles sleeping for the rest of my life now. Before taking lorazepam, I slept like an angel.
