I'm wondering if there's an insulin response to a carbonated drink? This sounds very plausible to me. The small intestine, in response to being stretched by food, releases hormones which trigger the production of insulin; this is effectively a preemptive strike against the blood glucose increase which usually occurs from a meal. (The pancreas also releases glucagon in order to ensure that the insulin release does not result in hypoglycaemia, resulting in something called the "Chinese Restaurant Effect" in type 1 diabetics: Eating a large meal can trigger a sharp increase in blood glucose even if the meal in question does not contain any carbohydrates.) While this particular effect has only been measured with food, not gas, I'd assume the same physiological cause would trigger the same hormonal effect.
