Welcome to tudiabetes, Marilyn. You've come to a good place to find both support and answers to a lot of questions you might have about diabetes.
I was misdiagnosed as a type 2 in 2011 at age 70 with an A1c of 11.5. My PCP treated me as a type 2 on oral meds for a year and a half. The meds didn't help sufficiently, so I ended up basically starving myself to get my A1c under 7.0. I lost 17 pounds I couldn't afford to lose, getting down to a scrawny 105 pounds before I decided I had to eat more carbs, regardless of my blood sugar. My doctor refused to put me on insulin, saying that she was afraid I'd try to adjust my own doses.
I asked about being tested for antibodies, as I'd read online about LADA and was suspicious that I might have that type. But the doctor didn't know anything about it and kept wanting to try something else. Besides, at that time none of the endocrinologists in our area would accept a referral for anyone with an A1c under 7.0. So I had to allow my BG to get over that if I wanted to see anyone who might be more qualified to treat diabetes.
As soon as I did see the endo the first time, he put me on insulin, even before the results of the antibody tests came back confirming LADA. He gave me a starting dose of Lantus and starting I:C ratio for bolus, but then was going to turn me back over to my PCP. As you might guess from the prior experience I'd had with her, I had absolutely no faith that she could handle my diabetes. I suspect that she just uses a set dose or a sliding scale with her patients, rather than using a carb ratio. So I bought the book "Using Insulin" by John Walsh and used the information in it to test and adjust my doses before going back to her three months later. Then I just told her what my doses were. Between that book, the diabetes message boards, and online research, I feel I have my diabetes under pretty good control, with an A1c of 5.5 to 5.9 ever since going on insulin.
You will no doubt get plenty of response to any questions you might post on the site, but if you wish to contact me personally, feel free to message me on this site. I'd be happy to be of assistance. I'm quite new to this site myself, so I don't know if there are any special rules about whether a new person can send messages right away. On some sites one has to be a member for a while or have made a certain number of posts first. Perhaps someone can tell us if that is the case here.
