Two caffeine-related questions regarding its effect on taste and sleep.

I like the 'sharp' taste of colas like Coke/Pepsi. Is that a function of the caffeine or that of a pressurised carbonated liquid? What I really want to know is are there colas that present the same sort of sharpness without stimulants in them?
Which brings me to the next question: if you're a regular drinker of caffeine(three cans every two days, hardly any coffee) and you consume caffeine, say, 2-3 hrs before sleep, will that affect your ability to sleep? So far I believed it did. But yesterday, I had a Coke 90 mins before bedtime and I don't recall greater difficulty in falling asleep. So, I'm guessing that my tolerance to caffeine took care of that. Is the sleep-interference due to caffeine's effect on the autonomic nervous system or does it depend on psychoactivity?
