Dropping my clinical sleep study, If You Get Up to Pee Now and Go Back to Bed, You Will Sleep Much Better Than If You Get Mad at Having to Pee and Try to Sleep Through Being Mad and Having to Pee. If anyone wants the full text of the study, it is pretty much just this post.
@GrimmReality At this point in time, the question yet needs to be resolved if you can fall asleep again faster if you do not open your eyes during that nocturnal excursion.
