Alexandre,
Why do you want to be diagnosed with ALS? What do you get out of this imbecilic back and forth between you with your narcissism and your hypochondria and the members of this forum? Do you have nothing better to do with your time than to stare for hours at your body, counting every twitch and mapping every dimple that you see?
You have a diagnosis -- BFS. At this point in the diagnostic process, ALS/MND is off your doctor's radar screen, so why do you keep bringing it back up? Are you too egocentric to listen to anyone's opinion but your own, or are you just too dense to realize that, in refusing to accept your good news and get on with your life, you are spitting in the faces of the people that you beg answers and comfort from.
You have been handed the key to your freedom, yet you toss it away as if it were a bit of trash. We'd pay a substantial price to obtain a medicine that would allow us to trade what we have for what you have, yet you won't accept it and, in fact, actively reject the notion that you have your answer and that you will have many more days to gaze at yourself and wonder. To me, that attitude is presumptuous and offensive, and makes it clear to me that further discussion with you by anyone here is certainly a waste of time.
No, Alexandre, I'm not going to answer your silly question about how long it takes to get a diagnosis and I would recommend that no other PALS here answer that question either. Our answers will not matter to you, and you will just twist them to say whatever is needed to support your half-baked theory of the week. So, from me to you, live long and prosper, young man and thank the heavens that you are likely to be able to do it.
