Hey TurboAngel,
I also used to sleepwalk. I grew out of it. But my parents got this little battery operated thing that screwed onto my door and set it before i went to sleep, if the door opened (aka i was leaving my room but asleep) the thing would beep pretty loudly and they knew to come get me and throw me back in bed
Sounds silly, but it would be a good way for your husband to be alerted so you dont hurt yourself again
