UT, do you mean that you have just had a diagnosis of Type 2 DM?
And, Clod ... you have so many reasons to be tired, but making sure your blood glucose is where it should be is a major issue to address. I haven't checked out the otc blood glucose meters so can't comment, but if you've had conflicting results, I'd suggest a fasting glucose AND a Hemoglobin A1C through a certified outpatient lab (i.e. ordered by your PCP, I imagine).
And if Minifob has results that are concerning, the same routine for him would give you a better view of things. A certified lab will let you have more confidence regarding test results.
If results say: Type 2 DM, there are ways to deal with it, without resorting to endless meds.
