Hi wings
I suggest you read some old posts here on AF forum. Many people in your situation did not tolerate at all glandulars or stimulants. If you have AF for several years it means you are too weak for them.
I would rethink the strategy taking two steps back. See if it's better with just vitamins or light supplements. Taking iodoral and selenium and MSM increase your rate of detox and maybe you're not able to.
I can't tolerate gingseng or stuff nor glandulars but did well on vitC and similar. Same with tyroid supplements like kelp...
Go back would be my advice and then start slowly IMO 4 caps of adrenal per day is too much
