Ambien made me sleep sex

Last night I had sex with my husband after our kids had gone down for bed. It was about midnight when we finished so I took an ambien and started reading a comic book to wind down. My doctor prescribed me ambien very recently because I’ve been experiencing extreme anxiety (due to work stress) and always have horrific thoughts swirling around in my head after the lights go out, depriving me of sleep. Anyway, after picking up the comic book, the last thing I remember was my husband telling me he was going downstairs to get a glass of water. It was a little before 1am when I last checked the clock. I slept in this morning until 9am and then got up with my husband to get ready to go out for the day with our family. I told him that I felt refreshed from getting a good nights sleep and that I was glad we slept before 1am. He looked at me really confused and said that we slept sometime between 2-3am after having sex two more times. I was gobsmacked. 😶 And, looking back, realized the last thing I remembered was reading a comic book while my husband went downstairs for water. Anything after that is completely blank. I told him this which caused him to feel disturbed and alarmed. I asked him to tell me exactly what happened and he did, describing everything I said and did in detail. I mean, what he described sounds exactly like the things I would say and do. He said that I was conversing with him normally and gave no indication that I wasn’t fully present. I’m so freaked out that there’s this hole in my memories! It’s like I peaced out and someone else took the wheel. Who was that if it wasn’t me? The feeling is surreal. Has anyone that’s taken ambien experienced anything like this? I mean, I’ve heard about people who’ve taken ambien doing things they don’t remember. I just wasn’t prepared for that happening to me. Obviously, I’m done with ambien and will let my doctor know. For the record, I don’t place any blame on my husband. We have a 21 year, healthy relationship founded on love and honesty. He’s just as distressed as I am and I know he wouldn’t have participated if I wasn’t a consenting partner.
