Just thought I'd update on the heart flutter. It lasted one week, and is gone. Went to MD, had ECG, completely normal. He listened to heart and did some exams, he felt cardiac was not my problem. I informed him of Primal, of course, he'd never heard of it - although he thought it sounded great. I told him about how I feel I may have been a closet, un-diagnosed celiac patient as I feel tremendously better now without the grains. He agreed and thought that my flutters were really GI system getting accommodated to my new way of eating. He recommended to continue diet, re-start exercise program and not to worry. Watch and report.
So, for now, problem solved with simply letting my body adjust to the new eating program of Primal. Feeling great, by the way, dropped 10 pounds now in 2.5 weeks. About 10 more to go to reach my ideal / goal weight.
