Need Some Suggestions

My older sister, who is also deaf, contracted Type 2 about 15 years ago. I have always been supportive for her with her type 2, but never really got involved in detail. Now, she has contacted me with worries of high blood sugars. She was only testing in the morning, and those results were in excess of the 300 range. I have purchased a One Touch meter, and instructed her to test 4-5 times a day, and send the results to me. She has been doing pretty good with testing, but her results constantly show spikes after meals, and before bed. Still 280-325.

I am hoping to recieve suggestions on how a Long Time Type 1, can help a Type 2 sibbling that is not doing well on Meds. Part of me wants to rip the Dr for not demanding more tests. Another part of me says. Put her on insulin. Because my dear sister has been deaf her entire life, she is a bit different.

Any suggestions are greatly appreciated
