Thanks for query,
At present you can not reduce your medicine dose but some alteration of dosage schedule should be done.
You are doing enough physical exercise and even then there is no reduction of sugar and bp.
So what you require is strict diet control.
Cut down complete sugar,avoid cold
drinks,ice creams, tea, coffee,chocolates,etc.
Take more salads and green veggies.
Cut down the salt.
Ok and bye.
