So sorry!!! I haven't had that..but I very rarely get heartburn to begin wth. Are you prone to it anyway? Are you on drops or injections? if drops maybe you should try fewer drops but more often - so you still get the same number of drops each day.
maybe split your food up more so you're eating more often?? just a thought. my daughter-in-law had that problem too and quit the drops. then went back on them recently and has not had that problem this time. same drops too. have no idea why. hopefully someone else who's experienced it can give you some other tips. hang in there.
