Dyspepsia after Dusk

Odd topic perhaps to make my first full SW post about - but sitting by the bed unable to lie down because I'll need to throw up, I need to whinge about why I've got a sudden attack of indigestion. Least I hope it's that. 😖

Other than industrial strength antacid tablets, does anyone have any good homespun or herbal suggestions? Might have tried some but there's always something new to try! I need help!
