You mentioned that you both ingest vitamin C, but the big question is: Are you ingesting enough? You may be interested in the following quotes from Dr. Thomas Levy, M.D.:
"There are very few human diseases or medical conditions that are not improved, to at least some degree, by the regular dosing of optimal amounts of vitamin C.
"The three most important considerations in effective vitamin C therapy are 'Dose, Dose, and Dose.' If you don't take enough, you won't get the desired effects. Period!...you will rarely ever fail to observe a dramatic response...IF you take a large enough dose for a long enough time."
"I am absolutely convinced of one thing -- when enough vitamin C is given...for a long enough time, vitamin C helps virtually every condition, resolves many of them, and prevents still others....Furthermore, I have never found a single article showing properly dosed and administered vitamin C to fail to improve the status of a toxic or infected patient.
The evidence unequivocally shows that mega-gram doses of vitamin C can prevent and cure a vast list of conditions that plague mankind. It is both inexpensive and completely safe. My conclusion: vitamin C is the 'Primal Panacea.'"
The "optimal" [oral] dose of vitamin C, Matulka, is summed up here by Dr. Robert Cathcart, M.D., "The clinical symptoms of...diseases and other conditions...are markedly ameliorated only as Bowel Tolerance dose levels (the amount that almost, but not quite, causes diarrhea) are approached." You may find, Matulka, that optimal dosage level to be many times more than either of you are currently ingesting. In this regard, you may care to peruse [at least the first ten paragraphs] of this article by Dr. Cathcart http://vitamincfoundation.org/www.orthomed.com/titrate.htm
Also, Matulka, are you aware that calcium ascorbate has only one-half the [electron] potency, gram-for-gram, as ascorbic acid? If you find it a bit too acidic in/for the stomach, it is an easy fix to simply ingest whatever minimal amount of sodium biicarbonate one needs to solve the problem.
Additionally, I think the following three quotes are very instructive:
"There are more than ten thousand scientific papers that make it quite clear that there is not one body process (such as what goes on inside cells or tissues) and not one disease or syndrome (from the common cold to leprosy) that is not influenced - directly or indirectly - by vitamin C." -- Dr. Emanuel Cheraskin, M.D., Dr. Marshall Ringsdorf, D.M.D., and Dr. Emily Sisley, THE VITAMIN C CONNECTION.
"The evidence unequivocally shows that mega-gram doses of vitamin C can prevent and cure a vast list of conditions that plague mankind. It is both inexpensive and completely safe. My conclusion: vitamin C is the 'Primal Panacea.'" -- Dr. Thomas E. Levy, M.D.
“I have never seen a patient that Vitamin C would not benefit.” -- Dr. Frederick Klenner, M.D.
I wish you the best of success, Matulka, in your search for better health [for both you and your husband]! If you have any questions, comments, and/or concerns about ascorbate/vitamin C therapy, please post them here and/or feel free to contact me privately.
