No Chance of phoning my doctor on the NHS. lol. Yes Blood sugar and BP seem okay. The linagliptin only has a subtle effect on BG which was what the nurse was aiming at. I'm on a host of other meds too so used to having side-effects. I was just surprised that it might take that long to show up. I must have been on them over 2 months now. Usually side-effects tend to show up fairly quickly. Anyway I am going to stop taking it as I plan to start a low carb healthy fat diet next week and if needs be I will move up to keto or fasting. I'll be testing to see how it all effect BG and will continue with the metformin.
