Six years out and feeling sick after almost every meal

Ok so I'm really getting desperate here. I am going through some weird symptoms where I feel these symptoms about 30 mins after a meal:

-Flushing in face and extremities

-Hazy Headed

-Headache

-Irritability

-Bloating

-Muscle Cramps

-Fatigue

-Heartburn (sometimes)

I do NOT have the telltale shakes/sweats/hunger of dumping, which I've had only a handful of times. Doesn't seem to matter what I eat: high carb, low carb, no carb. Whatever. I had a small bowl of just meat and cheese and still had it.

I've been tested for food allergies and taking acid reducers only seems to placate that one symptom.

This is having a profound effect on my QOL and I'm at the point where I don't want to eat anything and am considering just going back to shakes. This is after a couple years of poor habits creeping back in and I'm worried I permanently ruined something. Two endoscopies and a barium swallow have revealed no immediately apparent structural issues.

What are your lab results? Iron, ferritin, transferrin, b6, b12, copper... etc. I assume you've got results from a full blood work up which should be at least 10 vials.
