Hi dear thanks for your question,one important thing you have not mentioned in your question is your present blood glucose
level,your on sliding scale ,it is ok,To start insulin
or stop insulin on long term basis ,it depends upon your glycerated hemoglobin
that is HB A1,C.IF YOUR HBA1C
is above 8,go for insulin to control your blood glucose level ,if it is less than 8,you can continue with oral hypoglycemic agents.
