well...medically (and physiologically), you can use
insulin.
consult with your doctor(s).
if you are diabetic, it is best to get checked and managed before complications arise.
no offense to alternative medicine, but as a medical practitioner, its best to use approved
therapeutic medicines (the synthetic ones).
depending on your case, usually oral hypoglycemics are used first. then when you become
less sensitive to it, insulin is then advised.
Diet is the primary mode of control followed by
regular exercise.
