My recovery experience | If this can help anyone
Hi CFers,
I suffered from idiopathic, crippling fatigue and mental brain fog for around 15 years. I would start degrees, jobs and quit midway as I couldn't maintain the energy over time, an endless cycle of failures. The usual profile.
At some point, I started experimenting with fasting, elimination diet & food journaling, and there were suddenly marked periods of sustained improvements I had never experienced before - except with large dose of chocolate or coffee.
While it took a long time to map out (food has so many moving parts, just imagine playing Mastermind with 75 different colours!), I ended up conclusively associating immune overreactions to certain food items. Eat X, and I would start itching a few hours after, followed with maintenance insomnia and a period of rather impenetrable brain fog.
Complete abstinence of the identified foods raised back my energy from 2-3/10 to 9-10/10, albeit I need to stress out again that it took a gruelling extended amount of time as identifying every triggers is quite challenging, even when avoiding processed food to keep a solid oversight on all ingredients ingested.
I don't think this anecdote can help many people, but I'm quite convinced there MUST be at least one other desperate soul for which the CF is also stemming from the whims of an unattuned immune system.
Good luck!

I'm not mentioning the culprits because there is no universal pattern: my food intolerance are my own and knowing mine won't help anyone figure out theirs - if they have any in the first place.
