I have been taking glycomet sr 500 for many years twice a day. now my sugar levels are fasting 95 and post food 135 which was checked recently. earlier fasting was also high-130 and post food was 165. there is an improvement it appears. should I therefore continue wth the same medication or reduce dosage. I have been also diagnoised with CAD and have an angiogram IKORA3 years back. I am also taking NIKORAN-5 twice a day along wth glycomet. also take ECOSPORIN-75 after lunch. these medicines have been prescribed after my CAD diagnosis. please advise your opinion. thanks.
