Huh. My psychiatrist didn't suggest water with lemon juice (we don't tend to have ice, so I'd have to leave that out). She suggested sugar free gum and sugar free hard candies, neither of which I can have. We've got an awful lot of lemon juice, so I suppose I can try that. I suspect it would be bad for my teeth, though.

It is strange about the diet coke.

I'm wondering if the temperature of the coffee is what helps, so I need to try some tea, just to see.
