Lucy,
Thank you so much for sharing! It is wonderful that you have found such a healthy (non extreme) diet that is working for you. I am taking good notes!! Please do visit your doctor though. It is very important that you are under a care for your diabetes including annual eye exams, lipid profiles, etc. Anyone that would make you change the diet you described would be the WRONG physician, but do go see someone.
God Bless
Scott
