My take on Endos is that all the ones I have had (besides one who was ancient and needed to retire) were trying hard, but that they haven't been type 1 so they don't know what the day to day, hour to hour, minute to minute decision making process is like. Diabetes is a relentless disease and you have to make a good/right decision every minute of every day, basically.
Also, I tend to think that they feel some relief when they see patients who take care of themselves and have good A1Cs and control. They're so used to having to deal with trying to get patients to take care of themselves, that they relax some when they're with a patient who knows what they're doing. At least that's my interpretation.
As for treatment, RWC is clearly the gold standard. If you can achieve his level of control, that is amazing and the best thing for your body. For me, I don't have that self-discipline, but I am fairly happy with where I have landed.
I do eat cabs, but in an ideal world I would be having 20-80 a day rather than 100-200. Between a decent diet, exercise, and active control, I have a 5.8-6.0 A1C for the last 4 years.
The biggest piece of the puzzle for me was getting on a CGM. Having continual, real time day led to much better control of my blood sugars. I was even *****ing my finger close to 10x/day before I got a CGM, but a CGM makes such a huge difference in my opinion.
