I've been a McDougall disciple for at least 7 years. For the last 2 years my legs have felt like lumber, and I assumed this was a symptom of aging. Recently I read someone else's comment in which he described exactly the same symptom. 'Legs feel reaĺy heavy" and he mentioned neuropathy and wondered whether it was due to being B-12 deficient .
Has anyone else experienced this and what have you done about it? This symptom discourages me from taking long walks.. i take 500 of B12 weekly.
