I sleep-walk. Is there a safe way to wake me when I'm about to DRIVE or WALK UP THE STREET?!?!?

I know I have to go see a neurologist for my issue. I just don't have health benefits for another month and a half at my job. SOOOOO.... in the meantime, can someone divulge tips or tricks so that the next time my poor unnerved boyfriend finds me sleeping on the front porch in the rain or kissing him goodbye and trying to get into the car and drive to god-knows-where, he can do it without fear of flying fists and/or objects?
