I didn't quit drinking coffee cold turkey, but I have finally quit (after a long struggle!). I haven't yet gotten over the need for some caffeine in the morning, however I can get by with none - sometimes more happily than others On the mornings I do need a little kick, I will have a glass of iced tea. I know you were looking for suggestions other than green or black tea, but I honestly don't know of any Be careful though, because black tea can cause IBS symptoms in some people due to the tannic acid in it, and I wouldn't drink anything ice cold on an empty stomach.
Hope that helps a little. I was not a big fan of tea at all but I have gradually acquired a taste for it (even green tea - which I used to hate!).
