Teitelbaum has been proposing every cause under the sun for CFS and fibromyalgia for years. Go read some of his reviews at Phoenix Rising, where CFS patients talk about him. Apparently, he has lost their respect, so he is now trying to rebrand himself with his new theories of sugar 'addiction' so that he can keep selling books and vitamins. If his programs worked like he claims, that would speak for itself, and you would see the CFS patients there praising him...they surely do not, so don't be fooled. Taking unneeded cortisol, can be dangerous.
