No clue what to do.

I'm suffering extreme heartburn/possible gall bladder issues (no proof they just dont have any other ideas).. happened again last night 3am I've been up since.. the extreme pain is gone but I still have regular heart burn and been throwing up a lot. I haven't been able to eat in over 15 hours now.. zero interest and terrified that I'll be in pain again.

Cant think of something safe for GD that wont upset my stomach more :/

Any ideas?

Low sodium, nothing acidic, no grease or dairy... plus safe for GD and filling/long lasting ha.

Thanks in advance!
