Well done, nice to be in charge. I'm sure you'll get some great numbers with that weight loss.
I would just say make the most of your strips by testing in a planned way. The objective I imagine should be to use them to find out what food, and in what quantities, you can eat and still stay "low" 2 hours after eating that food. "Low" needs to be your definition, but I'd suggest it should certainly never be more than 7.8 two hours after eating, which is the max an average non-diabetic would record. A lot of us like to be below 7. As a pre-diabetic, you may wish to aim for these lower numbers.
I don't see the point in regularly doing fasting readings. It won't tell you anything much you can do anything about. Check now and again of course, but the main thing should be about food identification. Not just the food, but how it's cooked (eg, roast potato vs boiled, if you eat such things!)
Keep good notes and records as well so you can refer back, and check each food type twice with testing in case one reading was a fluke.
Finally, do make sure your procedure is right to avoid false readings. Wash hands first, and dry thoroughly. Don't squeeze too near the puncture site or you introduce other fluids which distort the reading.
Sorry of I've told you loads of stuff you already know!
Good luck!
