I often heard really exaggerated advice about how much water to guzzle every day. It got crazy.

One day several years ago, a nurse was taking vitals on me and told me to drink, I don't know, 48 cups per day or something? It was huge. And I regarded her with incredulity. So upon being taken in to see the doctor, and this was a physician that I really trusted and had a good long tenure, I repeated the advice and I said, "That's BS, right?" and she said yep, and I'll talk to that nurse...

I am especially wary of my fluid intake because I live in an urban desert. Therefore I must constantly drink fluids when it's hot to stay healthy and hydrated. However, I must also gauge my ability to find a bathroom while out on the road, and when you ride the bus, good luck with that! It might be 3 hours, or you're forced to make a small order at a restaurant to become a customer. So it's really a delicate balancing act of how much to drink. And also, remembering to use the bathroom at every opportunity!
