Hi Nausica. sorry to hear that your diabetes now needs insulin to be controlled. As a matter of interest do you eat a low carb diet - i.e. no wheat, sugar, pasta, rice, bread ? many of us have found that we can avoid insulin by making this dietary switch. so it might be worth exploring changing your diet to bring down your Hba1C.
I myself refused insulin or indeed any drugs and within a few months normalised by blood sugar. The details are in my signature , there are many other examples on here.
There is quite a lot of confusion about insulin in terms of treatment. If your body cannot make insulin then you need it. If it can but its not working properly then by changing diet you can reduce how much your body needs it and so possibly avoid the need to actually inject it and thus have to deal with your other worries like, telling your employers or your driving license.
Did your doctor actually check what your fasting insulin levels are? or give you any specialist tests before prescribing it?
Others will be along to give you more details about a low carb diet as a means of managing diabetes without drugs and the practical implications of injecting insulin.
