I have been having night terrors lately and also have been scratching to the point of breaking skin in my sleep. What should I do?

See your doctor. Sounds like you have anxiety issues...I would see your doctor to discuss medications...An antiosychotic may be a good short term solution...For a longer term solution, you should see a therapist.
DIET,,,,,,period. I know that i sound like a broken record becuse so many of my answers are the same. High calorie malnutrition is widespread in the U.S. And is responsible for a lot of "mysterious" illnesses. It mekes the brain irritable and that is produced in some people as night terrors or mares. A large amount of freudian philosophy is replaced by biochemistry that can only be upgraded by good nutrition.
