Hi Ashley
Peeing in the night is very variable, and depends on a lot of things, including how much and when you drink, several different medications, and blood glucose levels. Plus, of course other health conditions.
Personally, the thing that makes the biggest difference for me and my nocturnal trips to the loo is WHEN I drink. This is because my body tends to get rid of morning fluid intake during the day and evening, but if I drink a lot in the evening, then it makes its way out during the night. Seems to be pretty predictable, for me. But you probably have a different combination of circumstances which are combining to create your own personal bathroom timetable.
