It's encouraging that you've had good result from staying hydrated. I think it makes sense.

I've learned the hard way the importance of mental health as someone who had unfortunate pleasure of getting shingles in late 30s.

The first thing my doc asked me when I suspected shingles; "are you under a lot of stress?"

I nearly broke down and cried. I realized killed myself over work for nothing. For what? Never again. My outlook changed since then.
