I my BG was too high, I took fast acting insulin, which works immediately,
with a pen, before my meal. I took
Metformin before every meal. Then I also took Amaryl, a drug which jolts your pancreas into working again. Apparently, mine wasn't producing insulin any longer, though it was capable of doing so. Now that it does, I have insulin resistance again.
It took me a few years, but I've lost 70 pounds, and I'm off insulin. I went off the Amaryl in about 6 months.
