I had the same problem with acting out my dreams.
My neurologist prescribed 0.5mg. of clonazapam which I take every night, usually about an hour before bedtime. It has worked miracles for me. I no longer have wild or combative fights that had me kicking, swinging and punching the bad guy that was trying to hurt or kill me. I now have normal dreams and my husband doesn't have to worry that he'll be attacked in the middle of the night!
