My husband has been on ambien for years but only recently started having side effects. Getting up at night, doing things on the phone in his sleep, turning on tv. But the other night he took his pill as usual and then he just couldn't move or speak? This only lasted a few minutes. I was right in his face asking if he was ok. He was swaying like he couldn't keep himself up. He finally came too enough to make it to the bed. I sat with him to make sure he was ok. Later had no recollection of this. It was scarey. Was this just ambien amnesia? Why couldn't he respond? Other meds don't help much but I think the ambien needs to go.
