come sweet slumber

I wrote this third health article of mine using an elaborate vocabulary, in the style of writing that I enjoy best, but my words were toned down quite a bit, to a more casual level to include jargon like "booze" (which I never use), but I understand, as this magazine is called Month2Come after all, not Ladies Home Journal circa 1786, nor a C.D. Payne novel. Nevertheless I am happy with it and the message is clear and still the same, so hopefully the article will be of help, to those in need. Although on the opposite spectrum of added slang is the Shakespeare quote in the heading, which I did not write, nor do understand. How is sleep a season of all natures? What is "season of natures"?
