Type2 question

how exactly would you know if you had to take any more meds for this wonderful condition

I think it depends on the severity of your specific case as to whether you need to see an endo or if you can just see your general physician. I have never seen an endo for my diabetes, but I was also not on insulin, just metformin and a kick of sitagliptin for a while. I would keep in close touch with whoever prescribed you your current meds. And test frequently (fasting, pre-meal, and post-prandials) - that's the best way to know if your diabetes is well managed or not. Also, providing detailed, comprehensive logs of such frequent testing will give your doctor more information upon which to base their decision to adjust your meds or not, a better picture than just a simple fasting glucose level and A1C.

I have never seen an endo either but my aic average is 6.4 so time will tell
