After being put on 50 mg of Amitryptiline, which has sedative effects, during the night I would fall asleep on the toilet (no dignity!), "come to" in the living room, and would have zombie like walks.

As mentioned above, those accidents in a sleeping/semi-conscious state are a concern. In one incident, I sprained my knee and badly injured three toes on my foot... so glad I'm no longer on that A/D.
