Hello Mark,
Since you “survived“ the initial high dose of Pred, I would not change anything till your next appointment, 7 days more do not make any difference.
If you want other references to discuss with your neuro, you may see

One other thing, Time span is usually given to patients who have difficulties after the night sleep because it has a longer period of action (12 hrs versus 4 hours), you may think about that to reduce your expenditures.
Maurice.
