hidden heartburn maybe! Try heartburn remedies! Cut down on the soda, try fizzy water instead or plain water! Cut down on the tea, coffee, spicy foods etc..
cut down on sauces and pickles and the like…
i think the reason for this is because you're allergic to soda. plus soda is not good for you anyways. it's because your tummy can't handle all that intake. so that's the reason you barf all the time. or probably you have a sickness in your body. like cancer. but it's but to your group home or your parents to decide to let you go to the doctor.
