0.5 increase could be meter error: to me that looks like a very stable blood sugar level!Can I ask for some advice. I last ate at 8pm last night and then only very light meal and my reading was good (for me) at 11pm. I slept so much last night and only got up 15 minutes ago and my reading was slightly higher than going to bed even though I haven't eaten for 15 hours. It was 8.3 so up on last nights 7.8. Why would this be?
