Thanks for the concern, really. But as I said, this was only the third time EVER in my LIFE that I've had heartburn. The other two times were in my early twenties and were barely noticed (and were clearly induced by an excess of pizza and wine) :) I have been in great shape for years and am very very health, diet, exercise conscious. I would also certainly never drink soda and take malox for one bout of heartburn, yet alone YEARS of reoccuring heartburn! I do visit my doctor annually for an "overhaul" (I always fair EXTREMELY well) and if this problem did persist (and it seems to be gone completely since waking this morning) I would definitely take your advice and have this checked. Thanks again for your concern!
