There aren't many meals more challenging to bolus for than a Thanksgiving dinner you didn't make yourself (or sometimes, even one you did make yourself). You're not sure what's exactly is in each dish, and you're probably doing educated guessing in lieu of exact measurements. Even with tools like an insulin pump and continuous glucose monitor, it's tricky.
It's one of the many times that I'm thankful for having a CGM. (Thankful at a Thanksgiving meal? Weird.) I knew I'd need a combo bolus for this, and usually I'd take the majority up front, with only about a 15 - 25% tail over three hours. I'm not even sure how I arrived at that forumla, but since that scenario hasn't been keeping up its end of the deal lately, I thought I'd try something different - a 40/60 split over 2 hours, with a temp basal of +100% for four hours.
And guess what? I managed to slowly creep up to the low 180's, flatline there for an hour, and then glide back down to the 90's.
Boom. I'm ready. Bring it, Turkey Day.
