Hi all, I was wondering whether anyone would be able to give me an idiot's guide to the methylation block theory in relation to CFS? I am not scientific and my concentration is poor, so if anyone was able to explain it in very simple terms, it would be so appreciated. I've looked through some of the threads on it, but am still pretty clueless. Also, does the methylation block theory link in at all to the current research on XMRV, other co-infections such as herpes virus' etc..? Are they two completely different treatment approaches/theories, or could there be a link? Many many thanks in advance.
