Vicc,
Thanks for the info! Articulate and informative as always. If I might add one clarification, though - the "stages" described can and often do overlap. I only say this because I wouldn't want people to think that specific treatments can only be effective if one is in a certain "stage". I've found that treatment with B vitamins and antioxidants to be effective even in the last year, 8 years into it! I don't expect remission, but it has definitely helped my circulation!
