Dr Lam is a master in this. I once again found myself drawn to his writing in moments of despair. I think it's because however individual each persons experience of AF is, there is some explanation for it on his website.
He often makes reference to needing to work with an experienced physician which is a pull to his services as no-one else out there has the experience he does. I was reading his information about adrenal crashes and thinking there is no way anyone at their office would know exactly what adjustments would need to be made to successfully navigate a crash. The articles suggest you need a level of care or expertise that is simply not available from them or anyone else in the real world.
