i woke this morning to bloods of 12.9 had one crumpet and took 2 metformin and 13 units of novo rapid, went to work (cleaning 2 houses for 6 hours) missed lunch had a cheese omelette and one small new potatoe so didn't take any insulin but had 2 more metformin, took my bloods at 7:30 they were 17.3 so took a correction dose of novo rapid (6 units) took my bloods again at 10:30 and they were 14 so took an additional correction dose of 4 units novo rapid and 60 units of levemir - don't know what's going on as I've always been very well controlled
