After 2 weeks of PCS symptoms, I'm starting to feel normal now (although I've got a cold now). I'm about 80% recovered now. I still get dizzy and nauseous when over-stimulated, but no more headaches, and the general fatigue is gone.
This is interesting, because it took me about two weeks to "recover" from the original accident.
I'm so happy to have my balance and motor skills back. It's good to know this craziness can't go away if I get enough sleep.
