Egg_timer A wonder has occurred.  One of my own making, I might add.  Wasn't it me who said the 'T' in RUT was for Troubleshoot?  Well, I'm proud to say this time I've had miraculous results.

The new strategy I'm testing is injecting at least 20 minutes (to half an hour) before eating, and for about 10 days now, things have been GOOD.  It's absolutely Earth-shaking to see my post-prandial BG levels drop from 240+ to 140 and under. 

Now before you mumble, Duh Amy, everyone knows timing matters, consider: I used to be so insulin sensitive that ONE UNIT at breakfast sometimes knocked me below 60.  An extra half-unit could also make or break my afternoon.  And I used to get shaky within 10 minutes of a bolus injection, no matter how small. But those days are over!  Goodbye, honeymoon. Hello, pre-meal timing hassles.

What the DexCom continuous monitor helped me gauge, btw, was the insulin's current "speed of onset and duration of action" in my body -- vital information to which I was heretofore most certainly not tuned in.  Score points for (even the early) CGMS systems on that one.

What surprised me most was learning that so-called "fast-acting insulins" are in reality not so fast.  Of course, the renowned Dr. Richard Bernstein has been touting this fact for years: "If you're a Type I diabetic, fast-acting (regular) insulin can be injected 30—40 minutes prior to a meal tailored to your diet plan to cover the ensuing preventable rise in blood sugar."  OK, got that now.  And it works like a charm -- this week, anyway. 

The only thing I don't get is what went on before the "fast-acting" analogs came on the scene.  I always heard about those poor patients who used to need to inject a half-hour before mealtimes.  How inconvenient!  What if the food was delayed?!  But if today's "quick stuff" takes that long to kick in, how long did it take back then?  And when will we get a truly fast-acting version that will mimic the Phase I insulin response of a healthy body? 

Hmmph... for right now, we've got to appreciate Small Miracles where we can get 'em, I suppose.
