I was diagnosed T2 in July 2011, and was put on Metformin 3 times a day, it made me feel really ill. It was swapped for Januvia, and I haven't looked back.
I eat about 75 gm of carbs a day, and my readings are low and stable on that dosage.
I don't eat any grains except oats., so no bread, pasta or rice, cakes or biscuits, even supposedly wheat free ones have adverse effects, with bloating and water retention, and I very rarely eat potatoes.
