Folks are missing the point....for decades, the kind of insulin this guy was taking was the only kind there was...slow acting, yet people successfully managed their insulin regimes in spite of that.
The "fast acting" type is NOT insulin, but a new MODIFIED (chemically different) insulin with different properties.
I can't help but think there is more to this story.
