Yeah that was good. I learned a couple of new things. A large meal can lead to a low then high because it takes longer to digest the carbohydrates. If you only look at the carbohydrates and not the timing you'll have a lot of insulin acting too soon and not several hours later when you need it. Also never knew exactly what effect the fat in the meal would have. That seems a lot easier to handle if you have a pump. Gary seems like a nice guy.
I should have paid attention to this info when I was eating pizza last night, watching the game.
Thought I had bolused correctly and my blood sugar was fine at 11pm when I went to bed. But woke up in the middle of the night at 347! Darn pizza. (I'm sure it wasn't that I was a pig, eating too much pizza.)
one reason I miss NPH because it was pretty good at dealing with Pizza.
