Her medication can keep her dopamine level stable so that she is alert and functioning for a window of several hours.
The problem for her during the campaign was when she had an early event such as the morning 9/11 remembrance or when she had to give unplanned remarks late in the evening like she did on her plane the night of the sidewalk bombings in NY/NJ and she was about as functional as a zombie.
And if they try to ramp up her medication to extend the time during which she is functional, a side effect is seizures.
Very informative. I imagined it had something to do with the lessened demand of a non-campaign schedule, but you spelled it out succinctly.
Wow. Thank God for Pres. Trump.
