MTD, It’s great that your doctors are ruling out the “regular stuff”. If they make it through their list, and end up befuddled, I’d be interested in digging deeper (if you’re willing!). Many, many of us have weird stuff happening between wakefulness and sleep. I wonder if you ever experienced feeling paralyzed when this happens? Any auditory or visual hallucinations? I had them all! When you mention that fullness in your head, I immediately wonder about high intracranial pressure? Whatever is happening, please know it’s not just you! 😉
