I think the issue is figuring out the correct "lifestyle" treatment, as that word is quite broad. Research shows that an abnormally low HPA axis is associated with CFS, and in my case what worked was doing things to reverse this. This appears to be the case for other patients who have recovered.
I responded to rudeness with rudeness. Perhaps not constructive but my knee jerk reaction.
I don't have CFS but I can imagine they get an endless barrage of unsolicited comments such as "you need to eat more/less protein/carbs/fat/meat/vegetables/gluten/preserves/alcohol/fad-of-the-month and you'll be cured." I'm sure that people suffering from something as terrible and debilitating as CFS has tried all of that and more. Its the holier-than-thou attitude that gets under my skin.
We know (in general) humans can both survive and thrive on a wide variety of diets.
Sharing your personal experiences and what worked for you is helpful. Writing off research in medication with "why? you just need to change your diet" is not. Especially to those still suffering. It discounts real people who are really suffering and are still looking for answers.
