Heartburn

So I've already posted one other time tonight (this is super unrelated) but I have to ask: what are y'alls remedies for heartburn? I recently made a big move in July to Alaska (to be with my then fiancé now husband) and that's when I first experienced it regularly. It wasn't too bad. Pop a couple tums and drink some water I'd be good. But this last month/ couple months the heartburn has been so bad. I've popped like 5 tums over the course of a few hours and nothing. I can hardly sit let alone lay down because it's so bad, so I wondered if anyone out there had a good sorta cure they've manage to work out for it. Please I'll try just about anything at this point 😩
