I’m constantly striving to find strategies that (1) keep my bg as consistent as possible under changing conditions and (2) give me the most accurate use of my insulin so that I’m not carrying unnecessary IOB that I have to keep feeding later on to avoid lows. My ideal would be to accomplish flatter lines than I currently have, but not via using so much extra insulin that if I miss feeding an oncoming IOB-generated low that I’m going to be in major trouble.
So, I’m tinkering with taking an extra 5% basal from one hour before eating to one hour after eating (basically a two hour window). I am experimenting with this during a consistent, well-known meal so that I have an accurate view of what the 5% is accomplishing. And I must say, it has helped turn my meal spike gently downward much sooner than with bolus alone. Once I get comfortable with this effect, I’ll try it on other larger meals to see what happens.

Having said that, an extra 5% basal on top of a well-matched basal profile is impressive in its effect. It is something that I take seriously. However, an extra 5% FOR ME when my basal profile is becoming less effective due to insulin resistance from female hormones (I’m looking at you, progesterone), is SO mild. Progesterone in my system causes the Up and Stuck at higher than ideal bg’s. Once I’m getting Up and Stuck north of 150 I start adding 5% basal which very mildly brings my fasting numbers flat around 100-110. This is what happens in my body with my hormones. Same tool, but under different scenarios it accomplishes very different things. And I think this sort of thing might be useful for others, especially women.
