I do not have a problem with a sweet taste but I do have a problem with carbonation. I find I can no longer drink a carbonated drink daily. Oft times it will cause a burning sensation in my mouth that actually is painful. Also, carbonation seems to cause bladder and kidney problems as well now. For me, I have simply quit drinking carbonated drinks. Does anyone out there know of anything that will cause healing to the esophagus and stomach when they are irritated?
