I need some support with IBS and now GERD - Any advice?

So you guys know me, posted on here about bad reflux.
Taking 10mg Omeprazole, but my IBS has gotten worse.
I don’t think the two are mutually linked as it was bad before I was taking the Omeprazole.
I’ve had IBS for about 10 years, recently diagnosed through deduction last year.
I have tried everything diet wise.
I’ve cut out almost everything and I’m starving.
My Dr has been great helping me find what was wrong but now I’m left by myself in the dark trying to deal with symptoms that I always have.
I’m pretty much on the AIP Paleo diet, minus garlic and onion.
No coffee.
I“m always hungry and still have terrible IBS – D and C.
Any help?
Anyone found anything that really helps?
Taking psyillium husks, b6 and drinking water.
I’m so hungry – I just want to eat a massive burger with fat instead of salad and boiled salmon!
