Welcome to the Forum!
Read through the first three threads in the Type 2 Section, when you get a chance, if you have not already done so. These threads will most-likely help you a lot. Self education is one of the keys to successful management of your diabetes, along with a healthy / sensible diet and exercise. Basically, diabetes requires a life-style change for the better.
My experience with T2, indicates that the BG's won't come down, to a normal level, fast without the use of insulin. A gradual decrease will be your best bet. Look at it this way; You didn't become a person with diabetes overnight and you should not expect to be in the normal ranges overnight either. Diet and exercise are currently your friends. Good luck with your control and management.
