Acid Reflux

Kristin
With each pregnancy, I get pretty bad acid reflux at night when I'm trying to sleep. Normally, I can just drink a cup of milk (or three) when I wake up to go potty in the middle of the night. But for the last week or so, it's been so bad that the milk doesn't help and it's also been making me throw up in my mouth in my sleep.  
Is this normal? What can I take to help? 
I tried tums today but those did NOTHINGGGG. 
(Also, this baby is huge so she's really pushing on my gut. 37+2)
