I am wondering if Sprite (not only Coke) has caffeine in it as well. There was a time when i drank it, i had a hard time sleeping. today, i drank it and i "urinated a lot. i have tried to look at the contents but there is no caffeine written there. But honestly, dont the symptoms speak for themselves? I also have heard speculaion that Sprite does contain caffeine. So can anyone enlighten me?
