AFAIK, anything non-caloric to drink during those hours

>I was instructed to NOT eat or drink ANYTHING after 10 PM when I'm fasting for lab work. They did tell me water or BLACK coffee would be okay though.<

8 hours is probably enough, some docs will say 12 (I take insulin and 12 would be very hard), but definitely do whatever your doctor has instructed. AFAIK, anything non-caloric to drink during those hours is okay-- water, black tea or coffee, diet soda.

>I'm wondering if you take your meds BEFORE taking fasting blood tests?<

Ask your doctor.

>I have taken my blood tests, then taken my meds, waited for an hour
and taken blood tests again...only to learn the blood sugars are higher after taking the meds. So, there is something in some of my meds that causes it to be higher. Nancy.<

That's undoubtedly just your liver doing its helpful thing and supplying you with some glucose. After not eating for 8-12 hours, it thinks you're starving, and it's real worried your brain won't have enough glucose to keep you thinking and moving and your heart and lung working, etc, so... out comes some glucose, and your blood sugar goes up. As I said earlier, if you were not a diabetic, your pancreas would "cover" that extra glucose, but your pancreas isn't so good at that, so you see the rise on your glucose meter. AFAIK, this has nothing to do with any of your meds, but you can certainly check with your doc about that, too.
