Sam,
I go through phases where I test more frequently than normal. When I'm adjusting insulin rates or exercising a lot I will test more. Generally I test before meals so I know how much to bolus and I test once in the morning before my coffee (if I'm high I skip half & half). On top of that I will test if I'm feeling high or low so I know how to correct it (the # of units to inject or the # of grams of carbs to eat).
You're really lucky that you've found TuDiabetes so early after diagnosis. It's been a tremendous help for me, but I had to live in the dark for a couple of years before finding it.
