kate,

I just got back from a Brain Injury Support Group meeting at our local rehab hospital. The neuropsych gave a presentation on sleep problems. He said that the research points to low doses of Amitryptiline as being beneficial to increases in REM sleep. It sounded as if he also meant that higher doses were counter productive. He left before I could ask any follow up questions.

Just an idea to pass on to your prescribing doctor. Maybe he is already using this info.
