Happened to me the last time I was home.
Waiting for the rest to do the same. LOL. Actually for some reason this one had a cheapo battery in it. Can't remember why but I find 2 more 9volts stashed for just this reason.
If it works for you! If it was me it would be salt. At least that's my recollection of the way I liked eggs in grits - salted. Yep. I'm from up North!
