Brief Answer:
Please take a carbohydrate containg snack

Detailed Answer:
Good day,
Noted your concern.
Novolog acts in around 30 minutes and he effects stays for 4 to 5hrs. You must take a snack cotaining carbohydrate before you sleep. For exampe: 2 slices of brown bread or 2 wheatabix pieces or a cup of milk with 2-3 spoons of oats. This will help to maintain the blood sugar overnight. MAy i suggest you to check blood glucose again before sleeping?

Brief Answer:
Diabetes or infection

Detailed Answer:
Good to hear that. Your symptoms may be related to high sugars which can cause increased thirst and dehydration which cause headaches. ( noted that you had a blood sugar of 300 mg this evening). It could be also due to a viral infection
