So had my 3rd check up at the doctors Friday went from hb1ac 96 in April to last one being 44 in October, carried on 2 metformin a day but for the last few weeks really struggled keeping sugars up after breakfast till lunchtime so doctor said drop to one a day, anyway that morning after my appointment it dropped to 3.1 I felt awful my heart was thumbing so hard I felt like I was going to pass out! Phoned doctor she said to stop taking the tablets altogether and go and see her Monday. Any advice?? I'm now paranoid my levels are going to go up again? So far today been ok but not sure if out of my system how long does it take??? Also worried it's going to make me more hungry and put on the 2 and half stone I have lost over the last 7 months?? Anyone had similar experience?? Thanks xxxx
