My reaction to my diagnosis, which finally came yesterday, was similar to yours, Joe. Finally!! Actually my 1.5 diagnosis has been coming about for a couple months from my own process of reading and thinking (and driving myself nuts!). Like many people, I diagnosed myself.
I was stable on oral meds for a bit over a year from my Type II diagnosis when my numbers started climbing. Finally in February my doctor agreed to put me on insulin but only basal (and way too high a dose for me). I boomeranged between frequent lows and still being quite high after meals. I was really frustrated and started trying to figure out what was wrong. I was reading the diabetes book I have one night, a book that is 13 years old and I was reading the list of criteria for Type 1 and Type 2 and I started thinking, “could I be Type 1?” I came online to this and another forum and suddenly started reading about Type 1.5 LADA. The more I learned the more right it seemed. My PCP never heard of it. My new endo looked a bit blank but agreed to order a second c-peptide. It came back low like the first one. Antibody tests are not available here in Guatemala. She put me on Apidra a set dose and I learned carb counting and after crawling up a steep learning curve things started to come together with my numbers.
When I got my copy of Using Insulin delivered I was somewhat shocked to see full clear descriptions of Type 1.5 in a book written in 2003. Yesterday I went to my second visit with my endo and showed her my numbers and the book. I showed her my list of five criteria that I knew meant I was 1.5 (lost 40 pounds, low c-peptide, have another autoimmune disease, sensitive to insulin, and oral meds stopped working in one year). She nodded at each one and actually copied them down. She said I was Type 1. I said “Not 1.5 because that isn’t yet an official diagnosis?” and she nodded. Good enough.
