I searched and went to tons of doctors . All tests came out fine . I even did neurologicalhormonal tests . Anything ! Noone ever fully understood why I peed in my bed NO MATTER of the amount of water i drank I could not drink water for hours before sleep and still have some pee to wet my bed . Why didn ' t you just stop drinking ? Like sure , you ' ll be dehydrated , but it ' s pretty easy to just drink so little that you only urinate once a day . Much better than pissing the bed . <| sep |> In fact , for standard black and white eink devices such as the Kindle Paperwhite , their battery lives are measured in weeks , not hours . isn ' t a large part of that tidbit , the fact the kindle is kinda primarily meant for reading books , which doesn ' t change the screen too often ? I kinda doubt there ' d be much efficiencyif any gain over normal screen tech when you ' re playing a video , or game at 60 fps on your device .
