I have been a pre- diabetic for 26 years. It started when I was pregnant with my first baby. The whole time my glucose levels were low but want away after birth. Now I am 44 years old, 3 weeks ago I was told that I am type 2 diabetic with low levels (4.3), My doctor put me on metformin only and no other drug. This is what's going on now when I exercise, clean the house, or go to work throughout the day it drops fast 100 to 70 in 22 minutes and drops more after that. I eat or drink something very sweet to get back up but don't last long and it start to drop. I need help to understand what I am doing wrong? I an on a 2500 carb diet and I was told to eat 12 small meals a day but I feel very uncomfortable at the end of the day.
