Hi. Im liz and Im 19 years old and I already have really bad GERD and Acid reflux. Everytime I lay down i have to get up because I feel like im gagging like liquid is coming up my throat and it scares me so much because I have such a fear of getting sick. I get scared to even burp because I get scared to gag. I have tums but they leave an awful metallic taste in my mouth afterwards and Idk what to do I hate this feeling I cant fall asleep right now cause I feel like im going to be sick.
