Hi Sir, I am taking duotrol 1 tablet in morning and pioz 15 before dinner. Today I got my blood tested it is 164 mg / dl and pp 104. previously my fasting was 146 and 150 in last 2 weeks. Today I omitted at the time of brush and omitted water in stomach. Whether pioz 15 is not controlling sugar. What is alternative medicine in place pioz 15 or fasting report is high due to vomiting and indigestion. I am 71 years old and diabetic since 1976. Please suggest if pioz 15 need to be changed or fasting is due to vomiting and indigestion .I am taking pioz 15 for last 12 years
