Hi Agate. Yes, you're right. I have a lot of homework to do on this forum, haven't I?
I do have a dietician, and I use a MYLIFE Unio Nova to measure my blood sugar. But my doctor told me to stop using it. She wants to rely on the Ha1 blood test. I think that's what it's called. My readings are usually between 112 - 146 mg/dL. After exercise I have seen it drop as low as 96. Do you know what reading would be considered to be a "spike", and do you think that it's a good idea for me to go to all the trouble of riding my bike at midnight if I think I would be going to bed with too high a reading? Or am I just being silly?

Still, all this reading will keep me out of mischief!

Kind regards
Mike H
