I am Diabetic for last 5 years earlier I was on TRIBET2 morning & evening all was in control till Dec2012. Then fasting reading was constantly showing 225 & PP 240-260. So Doctor changed over from TRIBET2 to TRIGLIMISAVE 2LS Forte & ISTAVEL. Now readings are Fasting 120-140 & PP 80-100. Why fasting is on higher side and PP on a lower side.
