As a Type 1 diabetic for 9 years, and on an insulin pump for 5 of that, I can attest that it does take a lot of time to find the correct regimen.
And then as soon as you find it, it can just as quickly not be the right regimen anymore! LOL
I find my diabetes changes day-to-day. As a nursing student, with all the stress and sleeplessness that goes along with late night med sheets and never-ending careplans, and getting up at 4:30 to be out of the house by 5:30 to be at clinical at 6:30 two days a week, I find my needs are much different on those days than on my lecture days. And they are much different on my back-to-back 12 hour work days as an LNA.
Add in continuous migraines, 4 kids and a divorce, my diabetes is a CONSTANT challenge. What really, REALLY ticks me off is being labeled "non-compliant" when I'm doing my best to be compliant, and prevent/delay all the horrible complications I have to see on a daily basis.
So, as much as it is a continuing education for non-diabetics, it is as much a continuing education for diabetics also.
