I had my first completely blind day, where I couldn’t find the details of the meal I had in a TGIF, I went for a salad and duck, with a side of chicken strips. Never eating there before I didn’t realise the salad would have a sticky dressing and the strips were coated with something or other. Anyway was 5.4 before the meal, an hour from first bite I was 8.4. 6 hours after down to 5.9. (Previous 3 weeks has been about 120 g carbs) So obviously my choice was not great. Strange thing was I had a headache and felt groggy after meal is this a sign of sugars changing out of ideal range?
