it's never made any sense to me that we can't just trust our thirst. I guess that instinct can be corrupted (as hunger often is by bad food) but the idea that humans absolutely must drink a set amount of water today seems like bs to me.

I probably drink 3 or 4 glasses/day for most of the year. That includes morning tea. Way more in the summer and I'm outside a lot.

Also I find I'm much thirstier when I'm eating carbs than not 🤷‍♀️
