It can take up to 30 days for the meds to completely get into your system. This varies according to body type, but that is the general consensus.
I am a numbers person as well. I suppose that my profession has a lot to do with that. Shoot for this: 70-99 fasting (out of bed) and 70-120 any other time. Keep in mind that anything below 70 is a hypo and that an average of 140 or more for a long period of time can cause problems down the road. BTW just test before the meal and two hours after the meal. This will tell you what foods spike your blood sugar so that you can cut down on them.
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. Good luck with your control and management.
