I am 45, weighing 63 kg, BMI of 22, diabetic for the last 12 years. I have been taking Diamicron Mr. 30 mg (one tablet bbf) for the past 8 years. I achieved very good control when I started the tablet. Over the last two years, however, the HbA1c has slowly started to deteriorate, increasing to 6.5 (currently) from the excellent level of 6.0 (2 years ago). I also feel tiredness and weakness. My other reports like lipid, renal and liver are within normal limits. Doctor suggests me to stop Diamicron and try tiomate M (20 mg /1000 mg) one tablet bbf. Is this new tablet successful?
