I eventually received my delivery of my bg meter at lunchtime.
I took a reading before lunch which was 6.6. I've taken a reading 2 hours after lunch it's 5.8. I had oatcakes with mackerel pate (mackerel with full fat natural yogurt) and an apple.
Thanks. Been trying to stick to full fat yogurt, berries and linseed for breakfast, homemade soup and oatcakes with mackerel pate for lunch then a salad usually with chicken or salmon for dinner until I see what works for me.
