Hi @AllanE,
Whatever you do please do not go into information overload as that will not help.
Read through the basic information that daisy1 gave you on your other thread and that will be a good start.
If you do not understand any of that then please ask questions.
Gradually introduce some more reading around the forum, ask questions, take your blood glucose readings and keep a food diary.
Remember that stress, lack of or too much exercise, other medical conditions and days when nothing seems to make sense with your readings all add to the mystery.
