Yes, in the past I have sleep walked, talked and have reason to believe that I still do. A few times I have dreamed that I was looking for and found something that had previously been missing. Upon waking up, the long lost watch is on the floor next to my bed.
All past roommates and family members have been spooked at one time or another because of the talking. When I sleep, I sleep very deeply and when overtired, like in undergrad, required 10 separate alarms to wake my brain.
Congrats on your 46days. I swear that it took a really, really long time for my brain chemistry to stabilize after stopping alcohol at night. The good news is that I am now sleeping as well as I did when I was a kid. Hang in there.
