During COVID lockdown, working from home, I dramatically reduced my coffee intake while not replacing it with other liquid intake. I was literally drinking about 500 mL per day during lockdown. I also snacked on lots of almonds. When my son was born (still during lockdown), I literally did lots of running (jogging) around for various paperwork. 7 days after my son was born, I woke up, mentioned to my wife it felt a bit like I had been punched in the kidney the night before, and promptly found blood in my urine. Luckily, it turned out that I had a kidney stone, and apparently the jogging for paperwork shook it loose. (Cancer, kidney infection, kidney stones, and physical injury are the main causes of blood in urine.) Magnesium citrate is now my citrate of choice. It turns out I should drink at least 2 L of water per day.
