OK yeah so yesterday I kept myself properly hydrated during the day and slept some better last night. Still woke with thudding in my ears, but not as fast, or loud. And I was able to go right back to sleep after requisite bladder breaks, instead of sitting up and sudokuing until sleep took over again.
Thank FUK it is Friday. Because the mighty and beneficent FUK brings you Friday in his own FUKKING time.
