Tom,
Try the South Beach Diet for 90 to 120 days, and there's a good chance that your blood sugar level will revert to normal in just a few short weeks. My wife was in the same teritory, her doctor put her on some nasty drugs, neither of which had much of an effect at lowering her slowly rising blood sugar level. After 3 months of South Beach program, no medications, normal blood sugar levels and her dumb-assed doctor said "Well, I think you should go back on the medications as a precautionary measure." It has been more than a year now, her blood sugar level is still normal, still not on any medications and her doctor still don't have a clue.
Give it a try--it can't hurt, and according to the book, most everyone that was experiencing higher than normal blood sugar levels reverted to normal levels in just a few weeks after starting the program. Beats the hell out of pills, all of which have nasty side effects.
Good Luck,
Gary
