Just for the record, this is my body I'm experimenting with and I believe that I am free to do so. I'm not saying that any other type 2 diabetics should try this experiment. You almost certainly shouldn't and if you are thinking about it, talk it over with your doctor (who should talk you out of it).
I'm not a medical practitioner (I'm a software developer). Don't copy what I do. You have been warned. I take no responsibility for anyone as stupid as me doing things as stupid as the things I do.
