If milks not helping maybe some cream or fruit, bananas if you have them, I get it that bad too
thank you! and like coffee cream??
Try a Popsicle!
Avoid acidic food & greasy / spicy stuff.
Im not sure what that is being from australia, but im guessing so, like thickened cream you have on cake
Tums can help too it may not make it go away but can make it tolerable.
