Has anyone used lorazepam for their dementia driven loved ones. I don't like using drugs but she is going to fall out of her bed at the rate she is going. And this goes on all night long. Up every hour??? I am so exhausted and I just know there will be a point in my exhaustion where I don't hear her and I crash. Help? If I give her just one 5mg tablet she still tries getting up. 2 tablets scare me...and the nurse said I can give up to 4 (5mg) tablets.
