Sorry to hear that. I've been struggling with permanently being tired regardless of sleep and temporary weak muscles along other annoying symptoms, too since May. It has gotten a bit better now but I am still not entirely back to normal. I can definetely understand how you feel. I really hope you'll feel better soon, one way or the other.
I'm curious, how have you managed to treat yours?
Well as it's been said above there are no treatment protocols on this issue, so I've been refused any medical help.
So I had to do a lot of research. I realised that I had some kind of neurodegenerative disease that was slowly destroying my brain. At some point I couldn't even talk right. That's a terrifying feeling when you trying to say something but it all come out as gibberish.
So I started digging into drugs that can repair neurological damage. I know that official medical point of view is that neurons can't be rapaired, but that's not true. There's a class of drugs that can improve brain metabolism and in some cases can repair neurons. It's called nootropics. So I started trying out different nootropics (sometimes ordering online from other countried, faking scripts). Then slowly I started seeing improvements. I started getting more energy. My speach improved. So I knew I was on the right way. In a year I was able to get my speach back and my CFS was almost gone. In 2 years I have reversed my condition.
I went through a lot of nootropics. The ones that worked for me were: Nootropil, Cavington, Glycine (amino acid), ASD2 .
I've met a doctor once. He said there are no stupid people. There are people with brain metabolism disorders and you just need to find out how to treat it.
