I am not an "old timer" by any means (9 months and counting), but this has been a topic of many earlier posts (and some interesting "arguments" about the purpose of this board). No one that has ever posted on this board, to my knowledge, has authentically progressed to a "baddie" disease and other evidence from other websites (and from my own neuro) substantiates this. If you have BFS, you don't and will not progress to something more sinister. However, this does not mean that BFS symptoms ever go away once you have them, though some have indicated an abatement in symptoms. Many of the real old timers simply don't check back in to this forum- instead moving on with their lives with BFS. Some have checked back in and some are still here - and they typically indicate that they still have BFS and simply have incorporated it into their lives. It is benign, even though it seems pretty intrusive in our lives, and benign is what you (we) need to focus on (though its not always easy). And I would bet that very few of us don't have at least some fear in the back of our minds that it will progress into something more sinister (including me), even if our neuros tell us otherwise. To put it in a nutshell: the good news is that you are very very very very very very very unlikely to progress to something worse; the bad news is that it is not very likely to go away any time soon (though there are a lot of things you can try to minimize the symptoms - meds, no caffeine, supplements, therapy, etc - some including myself have gotten at least partial relief through one or combination of these).
