After having had hbaic readings between 6.7 and 7.6 for the last 5 years i have suddenly shot up to 10 after testing anything between 12 and 22 for about 4 weeks.This was on 80m gliclazide twice a day. After asking my gp what i should do i was asked to make an appointment with the DNurse. Soonest one was 3 weeks time.! As i was feeling pretty cr*p by then i saw another gp who told me to double up my gliclazide and see how that went and " get back to us in a few weeks". So although my readings have come down to between 9 and 18 i don't want to wait weeks as i'm worried now as i'm 7 weeks in to what are high readings for me. Anyone any suggestions as to what i should do now and am i right to be concerned?
