Your eating priorities are:
- quality
- proportions
- timing
Until you're eating clean (meat and veggies, nuts and seeds, some fruit, little starch and no sugar - no grains, beans or dairy), work out appropriate proportions of macro nutrients (protein, carbs and fat) for your activity level, timing is a non-issue. Don't worry about when you eat until you're eating excellent whole food in the right amounts.
The idea is to get some protein and fat for breakfast. If sausage doesn't work, eat chicken, a pork chop, some steak, half a hamburger, something like that.
Don't get me started. Your doctor's been led astray.

And your gerd is not caused by greasy food. It's caused by...
...your current breakfast. Grains are a huge inflammatory stimulus. Cut those out, I guarantee your gerd goes away.
None of this is medical advice. I'm suggesting you substitute some different whole foods for what you're now eating. Not supplements, not drugs, not manufactured food-like products. It's just food.
