I do it, but it scares me when I wake up and realize I was doing something I don't remember. I just have to realize that I am level headed, and know when I am up and about, I hope I am just as level headed then. The last time I did it I threw out my hot chocolate and brought it to the dumpster, (was told by a neighbor) and craved it when I was fully aware. I looked everywhere for it. So when I am like that I am health conscious at least.
Maybe this will help, just to know you are not alone.
