Hi Karl,
I was diagnosed as type 1 at 18 also. Bit of a blow, isn't it?
That was before the advent of web forums though, so you're much better off than I was. I had to screw up all by myself, but you show great promise by taking an interest so young!
As for the curry, it's much more likely to have been the rice that messed up your numbers. When I have an Indian meal, I always avoid the rice and the bread but have a couple of curry dishes instead. This keeps my numbers bang-on afterwards - never more than 5mmol/l.
In other words, it's the carbs you need to keep an eye on, not the cuuries!
All the best,
fergusc
