Having been a T1 for 43 years I had assumed that I knew it all, and my GP freely admits that she is no diabetes expert and we both agree that it is down to my consultant to advise as required.
However, when I was switched to Lantus a few years ago, my consultant never mentioned anything about how to test to see if that level was correct. Also, until coming onto this excellent forum site, I'd never heard of basal/bolus or insulin-carb ratios and the fact that they can be different for each meal. So this really created a new area of knowledge for me, and following many of the links in the postings took me to the Diabetes UK ebook on Carb Counting and Insulin Adjustment, the Carb Counting book, and also the detailed book on Using Insulin which I bought from Amazon.
So 6 months down the line, I feel I now have a good understanding on how to get even better BG control, and have experienced no assisted hypos for 18 months, and rarely have to eat any snacks between meals. Last HbA1c and chloresterol were lowest ever over last 10 years since I've been keeping a record. So self education has proven it's worth and shows what a wonderful communication and knowledge base the internet is when used wisely!!
