I posted something like this too!! Nothing is helping me!! I brush my teeth throughout the day, chew gum, drink water, but nope doesnt work!! I have no idea what it could be besides dehydration which isnt it because i drink so much water. Grrrrr!!!!!!!
Ive been drinking around 10-12 32oz cups of water a day..
U could try drinking Gatorade cuz u may need electrolytes
Make sure ur drinking alott of water and water based foods liek fruits, i was the same in the begining of my pregnacy i drank like 3 or 4 liters a day
You need a lot more water. I drink about 12-15 glasses of water a day now when usually I would drink about 8-10
