Last night I had 6 units of Novorapid then an egg sandwich. 2 hours later I had 2 units Novorapid then a very small snack. For the rest of the evening I could not control the rapid decrease in my blood sugar until after eating a combination of 4 Glucose tablets, a bar of plain chocolate, a cup of coffee and other snacks. Finally, I achieved the reading I needed to be able to go to get some sleep. During the night each time my sugars decreased luckily I woke up. Any help would be helpful thanks
