I know a lot of posts recommend drinking plenty of fluid when on medication but how much is enough? I don't get thirsty and I find it very difficult to drink extra water. Left to myself I probably wouldn't drink much at all but I make a point of having tea with breakfast and lunch, a cup of tea in the afternoon and coffee with supper. Is this enough or should I be drinking more? I do take a water pill for blood pressure but this doesn't seem to make me thirsty. I do not drink fizzy drinks as they don't appeal and I have an intolerance of cow's milk so all my tea and coffee is black. I am really interest in how everyone measures their fluid intake as it seems very subjective to me.
