@jack Here's the chart I found with the dosages:

I only began looking for information about higher dosages once I realised I'd need to go beyond the usual 60 mg recommendation for my titration.
It looks like I can cut back a bit in the evening now, though, so it won't overshoot by quite as much. Maybe 70 mg per day.
