Hi. Just a question please. My morning test is usually around 7.5 average. But I have found that if I eat something carby or sweet an hour before I go to bed my levels in the morning are much lower at around 5. Can anyone explain this please. On another note I notice my pre lunch reading is always very low. 4 or 3 or as the other day 2.6. I eat breakfast at 8am, then have Greek yoghurt and berries at 10.30 on my break. Then lunch at 12.
