Pre-bolus backfire

Diabetes doesn't like to play by the rules. Even when you do everything right, it doesn't always work the way you think it should.  This weekend was a perfect example of this. 

Friday night, I made a soup that has pasta in it. Typically for my guys,  pasta needs insulin after eating.  This time, however, injecting after he finished eating resulted in double arrows up on Dexcom for Jason. He didn't go super high, just higher than he likes and got there pretty fast. He was back down in range by bedtime, so everything was ok.

Saturday for lunch, we had leftovers of the soup. Since the timing was off Friday night, both guys decided to inject 15-20 minutes before they ate, which they try to do with most meals. We were guessing there wasn't enough fat in the soup to cause a delayed rise in blood sugar like most pasta. So they tested (both around 110), calculated their carbs, injected, and waited about 15 minutes to eat. Halfway through lunch, Jason's Dexcom started buzzing low, and falling. Seth had just pulled his sensor that morning and was waiting until after lunch for a new one, but he said he felt low too. It wasn't long before they were both shaking and sweating.  I sat there not knowing what to do because THEY WERE EATING!!  How the heck do you go low WHILE you're eating?? And since when do both of them have the same reaction to the same meal??

Sorry for the poor quality.  Dexcom receivers are hard to photograph!
This is from a different low...I was way too flustered to take a pic during that fiasco!

As I was contemplating what to do (quick carbs?  Glucagon?), I noticed I was shaking and a little sweaty myself. It only took a few minutes for them to start feeling better as the carbs from their lunch kicked in, but those few minutes seemed like a eternity to me. It may be a while before we have that soup again, but next time we'll try something different. Inject right before eating,  maybe? It's just trial and error, really. But eating shouldn't be that hard, and the error is just unacceptable.  We are learning every day, but there is so much left to learn for us to KDA.
