Dr. Wong, I am a diabetes of over 19 years, unfortunately, I have got Glaucoma and Diabetic Eyes sickness at these years too. I was tried to control my Blood Sugar as low as possible, recently my Blood Sugar wa at 6.9 A1C..... but the doctor of public hospital seems like don't want to make my Blood Sugar lower sand don't wanna change medicine types since he is afraid of my fainting if my Blood Sugar is too low. .... However, I really need my Blood Sugar to get a lower level because my Glaucoma eyes have been the late stage, otherwise, I'll get blind soon or later........I am very depressed for this, Dr. Wong, what would you recommend on my case >
