Well, one of the biggest learning curves about being on the pump is
learning to let go of micromanaging your diabetes (I was a hugely active
manager of my diabetes) and the let the pump with its algorithm perform its
tasks. The pump, when in Auto Mode, functions very differently from all
other pumps up till this one. I completely understand your concern about
peaks and durations of insulin effectiveness, but they've taken that into
account. While in Manual mode the first week while it was learning my
trends, my active insulin time was set to the insulin manufacturer's
specifications. However, when going into Auto Mode, the Active insulin
setting turns into a Peak Insulin time to accommodate for the continual
micro boluses. Because after all, after the insulin has peaked, it's not
going to do a whole lot more for you on its way down. I used to have
issues with pizza and bagels on a manual pump. Bagels were awful for me so
I cut them out of my diet because I could never manage how to prevent it.
For me, since going into Auto Mode, I have had a bagel and nothing
happened, the was a slight increase in my food. It is constantly adjusting
your insulin every few minutes to keep you in that target zone. It's a
very complex algorithm which is always adjusting to keep you in range.
Do you prebolus your meals? I do about 20 minutes because that's where I
got the best results and my meals are no longer a concern like they used to
be. I'd be happy to discuss this with you more if you want a detailed
description of being on it, the changes and the improvements I've had. Of
course, everyone is different, I am happy to provide as much information as
possible to aid you in making that decision.
