After 30 years of taking Lorazepam 1mg 3 times a day, my (present new) psychiatrist has switched me to Diazepam 5mg 3 times a day, after having said that the effects of the long term use of the Lorazepam has become too much and become a form of overdosing, and contributed to my depression becoming more severe. I have started on this, but have certain side effects. What side effects should be expected with this kind of change, after such a long time?
