'whenever I drink one coke it feels like I need to pee all the time?

Coke. The symptom you have is urgency. You maybe sensitive to caffeine or other ingredients in cokes. If you do not drink adequate amounts of water, this may lead to concentrated urine that irritates the lining of the bladder causing your symptoms. Try and stay away from cokes for a while, if the symptoms do not go away, see a doctor.
