I wonder what a typical day is like for you?
One of the big changes in managing type two over the past 20 years is the publication of research proving that diets such as low carb can have a massive impact, and the fact that the NHS has now recognised this.
I can't exercise due to other health conditions but going low carb meant I could avoid metformin, etc and lose a lot of weight. How low you need to go varies a lot, some of us can do it on 100g a day others need to go down to 20g and for longer to see improvements. If you do decide to reduce your carb intake, note that dropping carbs means you need advice from your diabetic team about adjusting your meds.
