I drink a gallon of soda a day and very little water. Is it ok to have orange ish urine and it burned.?

Not OK! Drinking a gallon of soda a day is not good for you. If it has sugar in it, it is fattening and bad for your teeth. Even without sugar, it isn't good for you because it has no nutritional value. Drink more water, milk, or real fruit juice in smaller amounts. If you don't feel better, see your doctor. Your urine should be checked for infection or other abnormal findings. Good luck!
Probably not. Urinary tract infections are common and can be related to hydration. Because soda contains sodium, it can actually rob your body of water.
