Green tea would be a good next step - a bit less caffeine (although I'm sure this could vary between brands) but still satisfies the need for a nice warm drink.

Green tea would be a good next step - a bit less caffeine (although I'm sure this could vary between brands) but still satisfies the need for a nice warm drink. I've been having green tea for many months now (after quitting coffee) and I'm not even sure it's worth stopping - I don't get any of the anxiety that I'd get with coffee, for example.
