Pregnancy cravings

Ok so I HATE coffee, I've tried alot if different types many times but I just can't bring myself to like it. Anyhow, I'll be 15 weeks tomorrow and I have been craving coffee like crazy!! I know about the whole 'no caffeine while pregnant' so does anyone know if there is some sort of substitute that tastes the exact same? Or even a little? This craving has been driving me insane!!
