Take a look at Jo's blog https://www.diabetes.co.uk/forum/blog-entry/the-nutritional-thingy.2330/ It's a useful introduction for the newly diagnosed. Keep an eye on your levels, use your meter to learn what different foods do to your blood sugar. Bear in mind that low carb can be very effective at lowering sugar levels and with your medication there's a possibility of going too low. Keeping a note of your meter readings along with a food/drinks diary can help spot things you need to change or cut out of your diet. It could also help your Dr figure out if you need more or hopefully less meds.
