Has anyone here ever done an extended TAG bolus for 6 to 8 hours after a meal? Why am I so hesitant to try this?
Hi Danny,
I have to use a 6 - 8 hour TAG for high fat pizzas or an 8 ounce or more well marbled steak. Since fat seems to slow the digestion of carbs for me, if my current BG is at or below target, I take a little off the up front bolus and add it to the extended bolus to stop from going hypo early. Looking at your graph, at around 3 hours after the meal your BG started to dip to near below target, so you may have benefited from doing something similar.
In my case, I would try adding up the total amount of correction boluses and the amount of extended TAG bolus. This grand total should approximate the total extended bolus I should have taken. I would then use this total with my 1.0 - 1.2 rate of delivery to figure out how long to extend. For MY metabolism, I usually have to extend the 6 - 8 hours. YMMV.
