I thought that I was doing brilliantly as I had got all my BS readings under 7.8. Nurse said see me in 6 months. Doc said see me in 12 months. Then I suddenly got a 17 reading, immediately took two more both 12.6. I had been extremely tired and cold night before, gone to bed at 19.30. What I did not expect was to feel faint just before lunch, reading 2.3. This all new experience for me. I do not want to bother surgery. When I felt very tired night before, I did not feel like making my usual low carb snack - crispbreads with Stilton, so I drank a can of Guinness. Any comments greatly appreciated.
