Hi Markp40 and welcome to the forums!
I am another newly diagnosed T2 and know just how you feel. You will no doubt hear from many others and far more experienced T2 than me, but I was advised to have a good look around the various forums here and threads, especially the "Low Carb" forum.
With that and with the info I had from elsewhere, it made complete sense to me to reduce my carb intake. I started a food diary and my first day (eating what I would usually eat) I had 197 Carbs in a day!! Over the next days - couple of weeks I have managed to reduc my carbs to 30-40 per day and found that mid-thirties is my level with the exercise I do. But I have also found that if I go below 30 it causes me problems.
I know some are able to take virtually no carbs at all and be perfectly happy - others simply cannot function below 70. IT IS a very individual thing and you will have to try things out for yourself. After the first few days, I never thought I would be happy below 70 carbs a day BUT at the moment it seems to be working.
If you want to look at some of my posts where I have given details of my diet/exercise etc. just search my username.
AND keep asking question - nothing is silly or can be asked too many times! Everyone here are friendly, supportive and eager to give you the benefit of their experience.
Best
Alice
