I went onto the pump in November and wouldn’t look back. I was convinced I could achieve similar control with obsessive MDIing and had a short but intense couple of months of internal debate as to whether the pump would be a good thing. It doesn’t guarantee perfect control and anyone who tells you it does is fibbing. What it does do is give the opportunity for much finer control using more advanced techniques than MDI can give such as square wave bolus and 0.1unit delivery. You may also find your HBA1c doesn’t automatically improve very quickly or even in the medium term but instead of peaking and troughing ski slope graph it’s a much smoother trendline that’s a sits little higher than your previous average.
