Thank you Bryanna, your post is so wonderfully thorough and thoughtful, AND SO INFORMATIVE. It is extremely helpful to get advice from one who really knows.
The citrus fruit warning is surprising - citrus feels so cleansing, but in future I will try to curb my cravings for oranges and grapefuits and ditto juices. It will not be easy, but I am very glad to be warned in time. I want my teeth to last as long as the rest of me.

With many more thanks,
