I've come to the conclusion that this is it for me. There will never be a cure. Never a treatement.
Have you tried any of the treatments which can often substantially help ME/CFS, patients, such as these:
B12 methylcobalamin injections (or transdermal B12 oils)
Methylation protocol
Low-dose naltrexone
Oxymatrine (antiviral immunomodulator)
Inosine (add-on antival immunomodulator with oxymatrine)
Epivir (for enterovirus ME/CFS)
Valcyte (for EBV, HHV-6 or cytomegalovirus ME/CFS)
Valtrex or Famvir (for EBV ME/CFS)
GcMAF as transdermal cream, capsules or injections (immunomodulator)
Tenofovir (antiviral immunomodulator)
Ampligen (antiviral immunomodulator, but hard to get and expensive)
IVIG (expensive)
Interferon beta (antiviral immunomodulator, expensive and benefits usually do not last)
Piracetam (good supplement for brain fog)
Nimodipine (good drug for brain fog and brain blood flow)
Methylphenidate (stimulant drug for brain fog and fatigue)
Modafinil (stimulant drug for brain fog)
Pyridostigmine (reduces or eliminates PEM)
D-ribose (to speed up PEM recovery)
Dichloroacetate (improves fatigue and brain fog)
Probiotics and prebiotics (if there are gut issues)
Rifaximin (for IBS or gut dysbiosis)
These treatments have a track record of helping ME/CFS, and are used by various ME/CFS doctors, or have been shown effective in studies.
You'd be lucky to find a full cure with these (though it sometimes happens). But it's quite feasible one of these treatments might move you up by one level on the 3-level scale of ME/CFS scale of:
mild, moderate and severe.
