Severe heartburn/GERD

Elise • Married to my highschool sweetheart❤️, 2.5 yo daughter 👧 and pregnant with my 🌈 rainbow baby 🤞
Anyone se experiencing horrific heartburn/GERD? I have never had this issue before but the past couple weeks at night especially but sometimes all day I get horrible heartburn and reflux that it makes me vomit and I'm miserable! It makes it hard to even swallow my one saliva! I take Zantac 150 2 times per day with no relief. 
Anyone elise have this and did you find any relief? Does it get any better in the second trimester?
