GERD & pregnant

Any one of you is diagnosed with GERD and currently expecting? How do you deal with the terrible acid reflux? Mine is so terrible, even if I eat a small portion, the heartburn is painful and I ended up vomitting everything out so I can have a peaceful night sleep. Anatacid that was prescribed was of no use. I used to take Omeprazole before I am pregnant but I am currently out of that meds already.
