Dear sir I can understand your concern
in my optinion your doctors approach is good and systematic
I would like to give few suggestions
in
diabetes control we need to consider diet and exercise as important as medications
but in your case since age is factor advising extensive exercise regimen is not possible
so mild walking is advisable if there is no comorbidites like
arthritis.
next comes diet which can be followed by splitting meals to five and avoid refined carbs
regarding medications
1. considering the new medications like DPP4 inhibitors is a very good option since they are not associated with
hypoglycemia as glynase
2.stopping glynase is a good option since there is associated cardiac problem.hypoglycemia is not good for heart.
3.regarding
insulin it's a good option but considering insulin like levimer or glargin is preferred choice than mix.
mix is associated with more chance of hypo than levimer or glargin
mix will work only for 12 hrs and this glargin and levimer will work for 24 hrs with very less hypoglycemia than mix.
kindly discuss this options with your treating doc
