Is it normal for morning readings to be between 7 and 9, with only water for previous 9 plus hours.
Fairly new no this and still trying understand why reading jump from 3 to 15 when have not eaten a lot or incorrect foods?
It can be very discouraging seeing these readings in the morning. My suggestion is to google 'dawn phenomena'. Basically (and I really mean very basically) the body realises that you are starting the day and need some energy after fasting while sleeping and 'helpfully' increases your glucose levels.
]These levels will eventually go down but are often the last to go down.
