A good idea to keep a note of what you eat too. I also have a hiatus hernia, and on the famous omperazole. ( sleeping may be iffy)
There are quite a few foods and drinks that make it worse , or add too much acid, unlike CLKD, fizzy drinks are a big no for me, black coffee, any spices, peppers, too much dairy. Some things like tomatoes and cucumbers I can eat in moderation. Obviously we are all different what works or Not for us food and drink wise.
Not sure bit the hernia came prior to me understanding I was in perimenopause or if it was unrelated. Probably the later, have always been bad with spicy food.
