Definitely Omeprazole, it was honestly so helpful for me! Mine got to the point I couldn’t even move, was throwing up, started taking it and instantly it went!
I had to mention this to my midwife as it was waking me up in the night and I was running to the toilet it was that bad!🥲 lansoprazole was issued to me and it’s taken it away completely!
Rennies really helped me. Mine seems to have eased off abit recently.
I’ve been prescribe omeprazol - best thing ever! Ask for GP for it. Nothing helped me, but these work wonders!
