It has taken two years and four months (and counting), but I am mostly better (maybe 90%). I'm back to work full-time and working productively. I'm driving (cities, highways). I'm exercising (fast treadmill walking and stationary cycle) at least once a day, usually twice. My mood is good. I've resumed my language studies. I've been on an actual holiday for a week. My sleep is better - not perfect, but better. I feel...close to normal, with some minor blips here and there.

I just wanted to share this. This community has meant a lot to me during my recovery (a special thanks to Mark in Idaho). I will post again with more information about my recovery and what has worked for me, and what hasn't.
