I'm glad your heart tests are good. Are you still experiencing the fatigue?
I used to have post-meal fatigue, shortness of breath, dizziness and headaches and also went first through a cardiologist. I thought I had "chronic fatigue syndrome", which doesn't explain anything. My symptoms were related to a damaged digestive system, so I am doing much better since I started digestive enzymes and vit B2 (anti-inflammatory for the post-meal headaches).
