@Terry4 … I completely agree with your premise on T1D insulin resistance. (T1) insulin resistance is the same as T2’s, or other combination types. Some of the underlying reasons for the IR may be slightly different with more or less complexity depending on the metabolic disorder, but taking an excess of insulin will:
A) Cause carbs to be stored as body fat, and
B) Increases your IR.
My solution was to cut back eating and insulin, which in turn reversed the trend. 
I can agree on that. !
Thanks for writing a clear summary.
Sorry Terry there was just a whole lot of information in your post,
It just made it harder to figure out what you were trying to say.
I would be nice if someone did study insulin resistance, an important topic.
I could have been more succinct with half the words but it would have taken twice the time. I pondered that comment for an hour or more before I started writing.
Writing is a creative pursuit and a work in process. I practice every day to get better. It’s not a linear path.
It is unjust. I don’t know one type 2 with a CGM.
When I was first diagnosed in 2000 I was put on Metformin. Couldn’t keep my sugar down so I elected to do insulin. Been on Lantus and Humalog forever. Nothing else. It’s not that I disagree with with double diagnosis. The nurse that was teaching the class disagreed with it.
Terry, I can’t tell you how my CGM has changed my life. I can take my blood sugar so many more times a day and correct when I need to. I stay in range longer.
Terry, I’m with Humana and it took forever to get the CGM covered but a nurse contacted me who put me in touch with one of the head people. I wrote a letter to her and she saw that it was done. I even got an apology letter from Humana because it took so long. Sometimes things work out.
Writing is a tool of conversation. It might take time but the connection is invaluable
From a passionate well controlled T2, hopefully there are others.
Actually I know many.
Tom I’m not understanding what your message has to do with my original question which was “Is it possible to change from type 2 to type 1.” I’m not analyzing anything
I got into the conversation mid stream, my take is no if you as other have said do not test positive for anti bodies you by definition are not T1. Follow the rest of the conversation.
Jim, I know when I stay on my low carb diet my sugars are great and I have to take less insulin. The thing everyone, who doesn’t have diabetes, needs to know is this diseases is a 24 hour a day, 365 day a year problem. And it’s very hard to do everything correctly all the time I’ve learned to do the best I can and not obsess when I don’t. 
I’m starting tomorrow to try to find my lab results. Hopefully, I’ll have some success and put the question to rest
@ Ester2 Just keep in mind that there are some type 1s that don’t test positive for the antibodies they test for. They haven’t figured it out completely. I believe though you will still have a low c peptide test though. Someone else here will know more about that!
