I find decaf coffee still gives me that caffeine buzz annoyingly - I stopped drinking coffee because it was affecting my sleep and now I find that I'm so sensitive to the caffeine that I can't even manage the decaf stuff.
Nice cup of herbal tea - that's what you need (even though I find most of them taste very much like warm tasteless water)!
foxinsocks - i drink green-tea quite a bit as well but some days i prefer a heavier drink like coffee. i'm not keen on regular tea and i'm not big on hot fruity drinks (except honey and lemon which i also drink quite a bit of now in the ongoing search for substitutes to reg coffee)
I love a good bit of honey and lemon especially when I have a cold. I actually found I had withdrawal like symptoms when I gave up coffee - god knows how much of it I must have been drinking to feel that way!
