skin felt different when I stopped being lazy about this

Right so I've been proper slack about drinking enough water lately — been so busy with exam revision that I'd just forget until like 3pm and by then my skin already looks a bit sad and dull. Started keeping a big glass on my desk next to my books and honestly the difference in how my skin looks by the end of the day is noticeable. Less that tight, vaguely grey feeling I get in summer when the weather's been warm and I've been indoors under artificial light all day. My mum always says drink more water like it's some revelation, and I always roll my eyes, but tbh she's not wrong. Nothing fancy, just actually doing the boring thing consistently.
