Half a year on a pump

• It's expensive. Every three days, when I change the pump tubing and the insulin cartridge, and throw away the various wrappers and old supplies, I'm reminded that the costs of pumping are awesome.
• You must pay scrupulous attention to what you eat. I stated under the pro's that I'm not doing any meal planning, but I do count every carb, and estimate how much insulin I'll need to give to "cover" that amount of carb. I did this with my previous basal-bolus program using an insulin pen, so it's not much different. But it is a hassle to try to eat, share the mealtime conversation, and simultaneously keeping track of how much insulin to be given to cover the carb. BTW, I almost always give my mealtime insulin bolus after eating, rather than giving a dose first.
• Too many features. That's said somewhat facetiously, as I've picked some of the features the pump can provide, and ignored others. But I sometimes wonder: if I turned on another of the zillions of options that the pump is programmed to be able to provide, would I make life easier, or more difficult?
• You still can go low. There's nothing magic about pumping that brings BG down to normal and stops there. If you O.D. on insulin, you will go low. Or if you exercise unexpectedly and don't adjust your insulin and eat sufficiently.
• You have a continuous reminder that you have diabetes. Carrying a device like this means you can't "tune out" your brain for more than a few hours. I now carry not only the pump, but a fingersticker and BG strips everywhere, and if gone from the house for more than a few hours, my entire spare-parts kit.

Was it worth it? For me, yes -- but it was (and still is) a lot of work.
