For the past 2 yrs. I've been hitting my husband in my sleep. We now sleep in different beds. I don't remember hitting him at all. I've had an MRI done and found nothing wrong. So no brain damage.My husband says I talk in my sleep. I laugh,scream and become violent. Any thoughts?

If it is a problem with brain chemistry it won't show up in an MRI.

Since it only started happening two years ago, I wonder if anything happened in your life that could have triggered it. For example, a traumatic experience, staring or stopping sleeping pills or other drugs/medicines or alcohol, being pregnant, changing your diet, etc.

Can you afford to go to a sleep specialist who can check you out?

You should also try to have a complete blood workup. Make sure you don't have any vitamin deficiencies, etc.

Does this affect how you feel during the day - do you find yourself tired or unable to concentrate, for example? Do you feel like you've gotten a good night's sleep?
