Your problem is probably the NAC and alpha lipoic acid. They create glutathione, which is good, but they burn up your methylation factors, which are already really low in cfs patients.
Alpha Lipoic acid is especially dangerous because it creates intracellular glutathione (with an intracellular methyl trap), and can redistribute mercury via chelation. A severe methylation deficiency makes your symptoms worse and can damage brain cells if continued.
Skip NAC and ALA, cause they could cause serious damage, and instead supplement with methyl folate, methyl b12, and a b complex to increase your methylation factors.
