Only a doctor can tell you if you need to go that route though. I'm assuming they make that decision based on your HbA1c being high or going higher despite being on a metformin, diet and exercise regimen.
You want to avoid this.
As a very tired parent of a type 1 diabetic I beg you to do whatever you can about your situation. You are lucky to have type 2 because it's something you can do something about. You have choices. You should exercise those choices.
About your type 1 child....just realize that your efforts are important and your child will be better off because of them. Although they might not realize it now :-)
Are you aware of the research linking diabetes and inflammation?
Chik-fil-a advertises that they use 100% peanut oil and I suspect Jack in the Box uses peanut oil. I don't eat at either one, not even to get salad.
Thanks for mentioning that peanut oil might be in nuts. I eat nuts everyday. I will check the labels.
