| Mick,
I'm on the MDI routine as well. I eat what I consider to be a "normal" diet, not a super low-carb diet. I bolus with Humalog whenever I eat anything, which my doctor refers to as a "low-tech" pump. The shots don't really bother me much using 31g. short needles.
I have looked at the pumps currently on the market and have decided to wait until the technology improves to automatically read and bolus like an atificial pancreas. Otherwise, I figure that I am really doing about the same amount of work and it's more expensive than my MDI routine.
Seems to be working for me. All of my A1c readings have been excellent (under 6.0) for the couple of years. |
