Ooh thats interesting that you notice such a difference depending on how much water/fluid you drink @Glisten !
I am pretty hopeless with drinking water overall -- always have been. But i try to be more aware of it the past 6 months or so and finding ways to make it more palatable. I also find it hard to just drink things lol ! 😆 i sip things over many hours usually.
But i've been "pretty good" this past week with drinking a litre of water on average each day (this does not include iced coffees!).
Longstanding joke with friends that my "water intake" was pepsi/coke. But i also tried not to drink more than 600ml of it a day (always sugar-free)..the exception to this was if doing sports or physical activity - then i might get thirst.
I think my body just doesnt tell me i'm thirsty much? I try now to just "drink something if i can stomach it", and not rely on my body to tell me if it thirsty lol.
