Speaking for myself only, I can tell you that I was not exaggerating anything - perhaps I was even underplaying symptoms.

The fatigue I suffered from a couple of years ago made it VERY difficult to clap during the annual year-end staff assembly. We just had it again last week and I was able to clap and chat and even left the room twice - I could NOT have done that two years ago.

Of course, the concussion I suffered caused my pituitary gland to malfunction and I'm only getting better due to HRT. Without it, I would still have difficulty clapping.
