Well, how spooky is this? As if by magic, poster spendercat in the Type 1 Diabetes section has just posted that she's got a Hypoband for sale on ebay for 50 quid.Sorry, new to forum so haven't figured out how to link to it. She says her daughter was using it, so maybe they can tell you whether it worked.
By the way, when I became diabetic 28 years ago aged 21, both me and my parents went through a riot of emotions. So will you and Sienna. Short period of thinking I was "disabled" in some way, but after that, dispelled it by just getting on with things, been backpacking in Asia for six months, long cycle trips with a tent on the back of the bike, carried on doing pretty much everything I did before, uhm, D-day. She'll be fine.
