Frances,Wow! I read that some people do that, and it's pretty scary (driving their cars). My friend Ambien dials me once in a while, which is pretty funny. The unnerving part (no pun intended on this board!) is that we don't realize we're doing it - so it's like amnesia. But, since it's always only been food for me (and no cooking, thank goodness - just snack foods), I haven't been too concerned. I did wake up once with half a piece of cold pizza in my hand (I'd had a few glasses of wine along with the Ambien that night -- definitely NOT recommended!!!). My husband had a good laugh with that one.But, everyone's different. My mom takes Lunesta which works great for her, but only allows me to sleep for about 3 hours and then I'm wide awake. Worse than nothing at all for me.I've tried everything else (acupuncture, Chinese herbs, herbal medications with Valerian, for instance, etc.), especially while I was pregnant with my kids. None worked well for me.Now, Xanax helps me sleep even better, but per my doctor is much more addictive than Ambien, so I only allow myself to have it for extreme anxiety, and as a sleep treat once a week.Mitra
