Hi kev - Supplementation for recovering from AF is a tricky area, and different people have different opinions on it. I've found that it's sometimes a matter of trial and error.
The program you're on is a good "starter" one. If it works well for you, stay on it. If it doesn't, try making some changes and see how your adrenals respond. Also, check out http://www.drlam.com, http://www.arltma.com

for articles with information on supplementation for recovering from AF.
Then there's the whole area of glandulars. This is an area of controversy. I had excellent results using them when I was recovering from AF, but some practitioners recommend against them. Some people find them to be too stimulating, but I found they had a strong calming effect on me. You might want to do further research and decide if you want to try them.
