Sleep problems

I'm trying to deal with my individual problems one by one.  Anxiety is down, no panic attacks, I quit Xanax and the only thing I can see left is my problems with sleep.  I've had these problems for years but I guess Xanax took my desire to do anything about it away.   It seems when I fall asleep, I dream of my family and while in the dream I'm cordial to them, on the outside I'm kicking and thrashing in my sleep.  I've hit my fiancee and thrown my cat while asleep.    The technical term for this is  parasomnias.  Everything I've read says this occurs when you are acting out what is happening in your dreams.  The problem is that I'm NOT thrashing or fighting in my dreams.   I'm not done researching but so far all I've hit is dead ends.  I don't remember how long ago it was that I slept well.  My fiancee says that last night I was rigorously scratching my butt.   If something doesn't change soon, I plan to call my primary care doctor and fill him in and see if he can't refer me to a sleep doctor.   I go to sleep tired and wake up tired.  Suggestions are welcome including those suggestions that come with a web link.
