How do you approach management for recurrent stone formers who sleep over 8 hours per day and fail to reach 2.5 liters of daily urine output on 24 hour urine stone risk studies?

I suggest the patient plan a schedule by which they drink 2.5 L per day. To get started, I suggest they set their phone to alert them when it is time to drink the requisite amount of fluid, preferably water. After a while, this becomes an automatic habit.
