Hi Frazzled - Martin didn't say he was medication-free - only that he didn't inject. Many many T2s don't have to inject either - if they need drugs at all - cos some can manage on diet and exercise alone - they may take tablets like the Metformin and the Gliclazide.
However if you are T1 - absolutely nothing other than insulin, does anything - because our bodies have stopped producing insulin. That's the simple difference between 1 and 2 - most T2s still produce insulin but then the body doesn't deal with it very well, so the body then has to produce shedloads more insulin so pumps a lot MORE into the body to do the job that a drip or two would have done before the person was diabetic. It ain't simple to get your head round! - so don't worry about not understanding most of it at the moment. In any case - because your Blood Glucose is so high at the moment - your brain won't be working as well as usual anyway - we become more quickly befuddled when we have too low BG, but too high BG does it too, just slower. Once your BG gets down a bit and you start getting your head round it more, it really does get a bit easier, honest!
Have they shown you the length of the needles you'll be using for the Lantus - they're tiny, aren't they? They need to be, cos insulin is injected just under the epidermis - it doesn't have to go into muscle or a vein or anything painful, and they're such fine needles, it shouldn't actually hurt. Not like a flu jab! LOL
