Don't be scared. Relax and just make sure you digest all the information so that you can make changes immediately to get the best results. Sugar surprisingly is everywhere so the biggest thing to change is your diet-low carb, and try not to have too much high fat due to your blood pressure.For some of us...yes...from a peak glucose reading of 23 mmols to 5.5-8 mmol within weeks.
Make sure you ask to go on the course to learn how to manage it and bokm follow up phone appointments and list all your questions.
Keep testing to twice a day for 3 months to learn how your body reacts to different foods (we are all different) any more is a waste of money and resources and you become to much obsessed. Keep a good balance!!
Good luck and ask me anything you need x
