Hello there.

Thank you for your query.

You have nicely given the current details of your health to help me answer your query.

When a person with your kind of diabetes for such a long time sees that the sugars are always uncontrolled, the doctor is left with no choice but start you on insu;lin as the other oral medications are not fully effective.
In your case to reduce the dose of insulin you can do it by the following few ways:
1. You can take moderate dose (discuss with your doctor) of medications from the category Sulphonylurea which you are not taking currently. By taking that it might help a bit (I am not very hopeful as already you have been past 20 years with diabetes) to reduce dose of insulin
2. In spite of doing the exercise you have mentioned here, if you are overweight then cut down your calories coming from food by 25 to 30% and this will reduce your need of insulin dose.
3. If you are overweight, even increasing the amount of exercise- cycling twice a day (total 60 minutes/ day) and per day of the week will help you further lose weight and bring down insulin requirement.
4. If you are overweight increasing the dose of tablet Glyciphage to total 2500 mg/day (must discuss with your doctor to rule out any contraindication to this) is one more way to reduce insulin requirement
5. If you are NOT overweight and do not have any known cardiac illness then adding a tablet known as pioglitazone in your medications (must must discuss with your doctor) will also help in reducing the dose of insulin
6. New medications which are expensive and not very effective can be tried like Vildagliptin/ sitagliptin/ GLP-analogues if money is not a problem for you.
If feeling excessive cold, please check your thyroid also.
I hope you got your answer. For any related query please get back to me.
