anyone else forget to drink during the day?

I get headaches before I have any feeling I'd recognize as thirst. Exercise and dry or salty foods will do it, but otherwise not so much. I've been this way as long as I can remember. Always associated it with how my hunger signals are also messed up, makes sense to me for both of them to be confused. All I do now is keep a water bottle with me all day. I take a sip any time my saliva seems thicker and after every few bites at meals, and once I established that habit it became more instinctive.

In winter I definately don't drink as much water but I up my tea consumption. As others have already said you know by the colour of your pee if you need more fluids.
