So sorry about that NMB. A lot in my family have it including my Granny, my Mom, a few of my aunts, one of my uncles, and now my Dad's starting to wonder if he's getting it as he had some sort of episode that scared all of us as we thought he was having a stroke or heart attack but it turned out it was this mixed with some stomach issues. The ones my Mom's side of the family has is chronic so it will just come and go.
