I have an embarring problem?

I sleepwalk. At night I get out of bed and do god knows what. I wake in different rooms sometimes I spill stuff on me. once I was eating a bowl of cereal I woke when I spilled the cold milk in my lap. My husband tells me things I do at night, walk the halls, open cabinet doors I get into stuff and make a mess and he says I don't talk I just stare. The next morining I have no memory of it. My uncle was bulilding a stairway from his second floor to the ground outside his house, he woke in the night walked out that door but the stairs weren't built yet, he fell 2 stories to his death. I had sleepwalking spells as a child once our neighbor called to tell my mother I was asleep on his doorstep. I had wanted to see his new fish pond the day before but mom woulden't let me visit I guess I really wanted to see that fish pond! now that im 30 im doing it again! Im affraid I might hurt myself or someone I love Any suggestions on how I can make this stop? Will it go away?
