What can I use to calm my Dad down at night?

Trazadone.....with Dr's approval of course.

Does he have opportunity for exercise...opportunity other than walking or pacing around to expel some energy? If not, it may help.

Pl. see a neurologist. My mother had severe dementia and hallucinations which were hurting the family. The neurologist gave her 12.5mg of quitipin and GABAPIN and we are seeing a total change within 3 days. No more hallucintions. I am glad I visited the doctor.

I made my dad some CD's of music that he used to like, some of which I had, and the rest I found on iTunes. Something about it really calms and relaxes him (most of the times). I'd also take the other suggestions and talk to his doctor, I know my dad was given a medication to help with the anxiety, and it seems to have worked to some extent. Hope this helps, and all the best to you.

Don't let one more day go by. Have his doctor paged today.

Talk to his doctor. He needs to sleep! Insist that the doctor give him suitable medication. Your dad is MISERABLE.
