Interesting. I keep a daily log of activities, medication and nutrition. In all of my setbacks there have been a string of overactive and emotional events leading up to the setback. It's right there in writing but I will agree it's hard to judge when the tipping point is coming. This is in contrast to what you're saying about waking up to it randomly.

As I've stated before light is a huge trigger for me so that usually plays a role as well. I do think emotional stress and solid sleep are the biggest factors in brain injury recovery. Isolating yourself could be helpful but we also need human interaction. Trust me I'm in a state of loneliness and it isn't helpful.
