Tennykins 5.8 is a great reading. Unfortunately (if you ar anything like me!) this means there is a bit of exercise in your future! The morning fasting reading is a bit high, as there isn't really anything you can do to bring it down. It was the final straw for me as it meant that my silly body was actually producing sugar while I was asleep (how f&*ked up is that!) SO it didn't matter what I ate before bed, what exercise I did, nothing would bring it down. Hence the insulin. You of course may be completely different and manage to do great just with diet and exercise! Just remember that sometimes there are things outside your control!
Good Luck
