Be careful. I thought sleepwalking warnings were in the patient drug literature by now.
I heard where once they woke up a person who was believed to be in a vegetative coma by giving him one of these pills in his feeding tube. They had hoped to calm down his spasms, but they got a very much aware, talking patient in a few minutes. The doctor, family, nurses were all stunned.
Warnings may be there now. My problem happened several years ago.
