Charlie: I have heard several times about older people getting B-12 shots and finding that the shots helped. I remember reading someplace reputable that nutrition can be a problem, especially for older people, and that B-12 shots can be useful for that reason. I myself was feeling perpetually exhausted many years back and a friend who had been reading Adele Davis said, "You need Vitamin B complex." I began taking it -- a good brand recommended by a pharmacist -- and that took care of the fatigue. I also use a nutritional drink recipe described by Adele Davis, and believe it has helped a great deal. Delda White ([log in to unmask])
