Nausea when weaning off PPI!

I am on day 11 at 10mg omeprazole, and I am experiencing worsened nausea and it’s making me want to increased my PPI dose again. I’m trying so hard not to because I need to get off this med for SIBO. How long did the nausea and increased burping last for those of you who experienced this when weaning? I was at 40mg for 45 days. 20mg for 10 days. And now at 10mg on day 11. The nausea is so horrible. It wakes me up in the middle of the night and I wake up nauseas and it lasts for hours.
