No idea if DVLA require testing on Gliclazide, when I was on that I didn't let them know, now I'm just on insulin I did have to inform them and they specify a meter that has a memory of a certain number of tests and even though I have Libre now I still have to have my meter on me when I drive. I don't think the app would be enough if you input the data manually?Interesting. Am back on Gliclazide and test as required. However my doctors practice says they don't believe in prick testing (cropped up when they changed meds disastrously) and will maintain no record of tests. I save my results on Contour Plus app and wonder if that is sufficient. NHS will not fund testing so how would DVLA get accurate info about testing. Could I lose my licence because of a useless surgery?
