jennifer, welcome to FlyerTalk...
I've never had heartburn (wouldn't know what it was if I had it), but had to see what was posted here. Now if I ever get it, or maybe wonder if I've got it, I'll know where to go.
Small point; in keeping with the 'spirit' of the posting hierarchy, this type of info is best placed under OMNI. I know it's kinda gotten out of hand with all the 'conga lines' etc., but let's try to keep the order somewhat.
Thanks...
