Yep-had this with all three- felt as if a pen had burst in my mouth. It went momentarily when I ate but then returned with a vengeance when I stopped- with a side dish of nausea which made it not Witt the bother. It will go of its own accord. Congrats in the pregnancy.
Oh God I can't believd I forgot that vile taste. Second vote for anything salty. Also ice lollies, fizzy drinks, sorbets, fruit, raw veggies, refresher-type sweets, mint tea, bitter lemon drinks, lemon squeezed into sparkling water. These all helped.
I have this too and find that orange juice or oranges makes it worse
I've found brushing my teeth helps (when I'm not gagging around my brush) and homemade lemonade (lots of lemon juice heated with sugar then topped off with lots of ice cold water and sprigs of mint) works wonders. I could drink gallons of it!
