I had been taking Ambien along with Lexapro for the last 3.5 week with no complications. Then on Monday morning I got up and ready for work as usual and half way there (a total 10 mile drive) I started seeing double and that's pretty much the last thing I remember except, I do vaguely remember hitting the guardrails (and wiping out the side of my car $2500.00 damage). I remember nothing after that until a short time after I arrived at work. I am very fortunate that I did not hit any other people or cars and that is the good news. I do not remember the last 5 miles of the drive or unloading equipment from my car. A while after I woke up so to speak and wondered if I dreamed crashing my car. I went out to check and saw that it was very real. I reported it to my doctor who was shocked, but reluctant to blame Ambien. I was not like falling asleep. It was more like being in a trance. Very scary and my insurance company is sure to either raise my rates or drop me. Abien users be warned!
