One time I went on a dating app date, was nice. Met her again at a party, went on for drinks just the two of us, made out, she walked me home. Then I had a horrible, horrible bout of depression where I didn’t check my phone at all for about two months. So, that’s one instance of what’s going on in the persons mind.
I have a friend who pretty much drinks nothing but tea. No water, coffee, alcohol, soft drinks etc. And he does get his 2-3 litres of fluids per day in like that.
