I have been struggling with type II for several years now. For the last year the medication (Metformin, Glipizide, Gliburide, Insulin) stopped working. Glucose levels off the chart, 250 to 500. I have started seeing an endocrinologist and he has diagnosed me with insulin resistance. Im off of all the meds (they don't work) and riding about 100 miles a week. Fasting glucose levels have droped about 30 points in the last 1.5 months. Everyone is different. My Doc has told me that I am way above where he planned on me being at this time. Hopefully with the shedding of another 30 pounds my levels will start to look normal.
Good luck to you
