insomnia
"I have had amnestic episodes: I have had conversations with my spouse that at time were extremely distressing to him- the next day I would have no memory the discussions. I have walked in my sleep. A few times I was saved from hurting myself e.g. thinking (telling him) that I was going to the bathroom but starting to sit down before I got there and luckily caught by my husband - or I might have struck my head if he had not caught me.  ( I didn't remember those times as well). But my strange behavior started to worry my husband -a loving and devoted spouse.I have gone onto the internet while on Ambien and bought items. At first I was puzzled by unexpected deliveries of whatever I had bought- I realized the impact of Ambien on my life."
