I know there are other threads for fbgs, and for highest/lowest readings in one day. But I've noticed that over the last few weeks my fbgs are often higher than my bg readings after my evening meal the previous night.
eg Monday night 7.0, Tuesday morning 8.0.
Tuesday night 5.9, Wednesday morning 7.2.
I forgot to test on Wednesday evening.
I'm currently in gran canaria on holiday and cant get mine down...17 before bed so I injected fiasp and levemir which should have brought it down to 6...I woke up at 25.4!!! My insulin is kept cool and injection sites alternated. Been like this few days now and I've no explanation for it!
