7.8 and I would if on two doses just take my morning dose and correct during the day if necessary.
If one dose I would half it and give a 1/2 sized dosage now...
Again I would be very careful as this could impact on the readings tonight if your insulin is lasting 24 hours.
In your position I would be contacting my DSN for their advice.
This is only what I would be doing... Obviously not knowing your body, doses or time of being a diabetic it is very hard to tailor whats written specifically to yourself..
