Hello, if this is your first venture into the D-zone (!) in any way, then this is an excellent place to be for information, encouragement, support and advice from those who have been living in the D-zone for a good while. (I'm pretty new myself).
One thing, as a newbie too, I found very very helpful was to get myself a glucose monitor off the Internet (under £20 but like razors, they make their money on the test strips you have to buy continually!).
Knowing I could test my BG levels before, after meals, fasting, exercise etc, is really helpful. It's both a warning, and a reassurance, and helps you explore just how the 'triangle' of eating/exercise/drawing on 'stored sugar' (body fat etc) interacts, and that helps one manage the whole situation.
There's huge expertise from the 'old hands' here, so you can ask any question and get a good answer from them.
