Get Sleep not just the day before but both days before the debate... Maybe even 3 days. His reaction time will be better if he does.
Along the lines of getting sleep, they will usually release BS the night before the debate to lessen his sleep the night before thendebate.... START GETTING SLEEP ALL THREE DAYS/NIGHTS BEFORE THE DEBATE.. Reation time and him just being him are the most important things for his debates against Hillary.
