I had this horrrrrrible all day and all night, my OB said to take Prilosec OTC every night before I went to bed and ever since I've started it I haven't had it since, it seriously worked miracles, tums worked for a while but it'd come back 3 hours later
You can try a glass of milk or tums , they work form me sometimes. Im 32 weeks today and it get wrose for me the bigger i get. Good luck.
