I found out I have type two diabeties in july. The doctor tried giving me metformin but no results so he we found 15 iu's of humulin 70/30 twice a day to help. It brought my a1c from a 15 to a 9.6. I still am confused why my glucose levels are like a roller coaster, I try to stay on a low glycemic diet. I was also told I should quit smking but have started gaining weight since on inulin. How can I control my weight and stop my sugar going from too low to too high.
