I'm currently in NC for several months and was dx'ed here. Met with 2 Diabetes Educators in 2 cities. The first said test once/day (she was a T1 and adamant as T2 that's all I should do) and gave me a sheet with how many servings of carbs I should have (3 per meal = 45 each, 1-2 per snack).
Yup. Regional and institutional differences abound, just within the U.S. alone.
Here's where
I lucked out, perhaps because I was hospitalized and put on insulin right away. They wouldn't let me out until I'd learned to use my meter and shoot insulin, and they sent me home with all my new gear.
I was told to test 4x a day: Wakeup, before meals and bedtime. But they're actually happy I test more often.
I've been able to get my insulin dosing adjusted by email so I could eat, and advised me to tweak according to my best judgment! So my HMO does some stuff extremely well.
On keeping under 140, however ... not so much. Of course, my True Evil Plan is to get below 110 and stay there.
That said, on my last phone consult I explained that I'd felt awful for a long time, and all that stuff comes back as soon as I get anywhere near 150 (Truth). Since they know I test, and have not had any lows, they've stopped arguing.
I've heard of them, but I'm not in a financial position right now to experiment with anything additional to my diet and everything I check out has been way too expensive. Maybe someday when I get truly sick and bored of my diet.
I chipped my sweet tooth somewhere along the way. It's just a stump now. But I'm devoted to my sinful mocha latte.
Since I don't sweeten anything else, I could afford little $5.00 jars of stevia and lo-han (luo-han). Neither of them spike me, though of course Your Meter May Vary.
Stevia is the sweeter of the two. Sometimes it tastes bitter to me. Less is better. Before The D, I tried to plant it (ran across 'em in the herb section of the local nursery), but it's one finicky little weed. Fresh or dried leaves can be used in stovetop cooking.
Lo-han has no aftertaste at all (to me). More is better; it's about half as sweet as sugar. It's also a tad more expensive and not so easy to find. I found it in a health-food store under the SlimSweet brand, and the $5.00 jar was the only size they had.
