I'm finding that my days are gradually getting better - I'm at the point where for much of the day, I have minimal or no symptoms, at least when I take it easy and stick to light activities only.

But my evenings and nights have been somewhat of a different story. Some evenings I start to felt a bit of instability - not a full-blown triggering of symptoms, just an intimation of the headaches/wooziness I initially had. This feeling is more noticeable if I'm working closer to my physical/mental limits during the day. However, it seems to recede after I lie down for a half hour or so. I'm also still having unusual and/or vivid dreams, with not a lot of continuity between dreams. Finally, I seem to be waking up once or twice at night, sometimes with a mild headache and/or some anxiety about the injury. I might switch on the light, go to the bathroom, read a little or go online briefly. This seems to help me settle down. Then I'll go back to sleep, typically waking up for the last time around 7 or 8 am. Once I'm up and about, say by 8:30 or 9, I seem to feel better, and, for the most part, this improved state seems to hold throughout the day, unless I overdo it.

Does anyone else notice a similar pattern (ie, better during the daytime, with some regression and/or anxiety at night)? Is there anything I can do to mitigate the down cycle and promote rest and healing at night?

Also, my naturopath mentioned that there is some evidence supporting the use of melatonin to help people heal following a concussion. I know some people use it to help them sleep. Any thoughts?
