can i ask you a question please. Would you say Dukes diabetes is under control? The reason i ask is because of the back leg problems he has, neuropathy i suspect. We give him 2 Doctors Best vit b12 methylcobalamin 1500mcg capsules daily and a drop of folic acid but does the BG need to be under a certain number before any improvement is seen. Obviously it will take time but will it be working to it's max with his numbers as they are now.
