As long as I am hijacking this thread, some conventional thoughts on diabetes as I know them (of course, you are probably an Endocrinologist, if so, EXCUUUSE ME!)
Cake icing tubes v. glucose tabs? Yes, if you can't find any (Martinique anyone?). I get 50 glucose tabs for about $5 on-line v. $2 for a tube of icing using refined sugar - I'll take the glucose tabs anytime. I know what I'm getting, can accurately control the dose and it's fast acting. Normally 3 tablets (30 cents) gets me from a 60 BG reading to 95 in about 15 - 20 minutes.
I am testing 6+ times a day, I should never be unconscious, but I do have a glucagon set (yes, they have their own issues). It's similar to an epi pen; mix it and jab it in a leg, arm, wherever - no IV required.
Sorry if you were put off by my, "Say NO to brittle diabetes as a term", but this term is like waving a red flag in front of a bull. 'nuff said?
