12.2, retested other hand - 10.8
Likely causes include:
Overdoing it yesterday as daughter home from uni.
Eating more carbs than usual, including sushi which didn't spike BG significantly itself but overall a rather carby day.
Possibly incubating cold which hubby had a few days ago.
Feeling rather run down, was bitten by an insect and eczema has flared up in that area.
Lack of sleep. Went to bed "tired but wired".
Eating v late. Wasn't really hungry but needed food with meds. Put it off for a few hours hoping hunger would kick in but it never did.
