Hi Tracey
Have to agree with Debloubed and Kegstore, I think that a pump would be most suitable for you, given that your control and hba1c are little erratic. I have also had diabetes for 26+ years, and no very little about pump therapy, except what I have read hear on this forum.
A few years back, I use to see a consultant at my local infirmary regarding my eyes. This chap had been type 1 for 30+ years, and had been on a pump for 10 years. We would discuss all things to do with diabetes, and he told me that he changed to pump therapy due to erratic bg's and hba1c's. Having changed turned his life around, and enabled him to control his diabetes better, with hba1c's of 5-6 region.
Also Tracey, have you ever thought of asking about the DAFNE course. I did one back in October and found it extremely useful. As I say, having had diabetes for a number of years, I was a little sceptical of learning anything I didn't already know, however I came away with a wealth of knowledge and a better understanding of how to adjust insulin with carbs. As a result, I am having fewer hypo's and have improved my bg readings. Overall, it is a very worthwhile course.
Try and find out about the pump therapy, or indeed the DAFNE course.
Best wishes
Nigel
