I have been a sleepwalker ever since I was a child. I've done everything from run a bath to cut my own hair in my sleep. I don't think I do it anymore. But at least did it well into my twenties.

Maybe set up some bells on the door to your bedroom and when you open and close it the bells will bring that would wake your husband up. Or you could get some of those fuzzy handcuffs and handcuff yourself to the bed those are things that I would do if I felt it was necessary
