Taking 1000mg metformin twice a day and glicizide 80mg twice a day. Lowest reading is 13.8 and highest is 24.2. Tonight 2 hours after eating my sugars are 18.9. I literally don't know what to do to bring them down. All I had for dinner was some garlic chicken and green veg and a small amount of Greek yoghurt with honey. Surely that can't be that bad?!
