For me, if can maintain 6.2- 6.5 everyday already very happy liao.
Just eat normal, exercise a bit, don't eat so much rice, chocolates, ice cream or drink coke.

I can take meds to control if I chooses but as long as it is still below 7.0, I will not take it. Exercise, eat less rice more vege, oats every morning and take less sweet stuff, that is okie for me.
