Newly Diagnosed 11-25-09 Questions

As stated in the subject, I was diagnosed the day before Thanksgiving. Went to doctor to get some antibiotics for an infection in my foot. Stepped on a nail. No tetanus, just an infection. Bg was 248. Doctor freaked and sent me directly to the hospital. On IV 4 hours later then in surgery 1 hour after that. 1.5 CM incision on bottom of foot. Bg was as high as 251 at check in time at hospital. A1C of 8.0. Endocronologist came in and told me I have type II diabetes. No tests other than the Bg and the A1C. I have done tons of research since then and now know at least something about the disease. Was sent home on 20 units of lantus in morning and 20 again at night. Went back to doctor with Glucose meter in hand, doc looked at the numbers and cut me back to 10 units at night. Also prescribed Metformin, one AM and one PM, no idea of the dosage. The entire time I have been home from the hospital, my morning readings are between 76 and 85. Every Morning. Readings befor each meal between 80 and 90. I have entirely changed my diet. Believe me I was not eating close to healthy before this.

I am sure my Bg was high at doc and at check in at hospital because I had eaten just before I went to the doctor. Drank a soft drink with the meal and another on the way to the doctor.

I know that an A1C of 8 is high. My question is, could my A1C have been that high just because of my BAD eating habits? I think my doctor is just quick to prescribe medication. I have taken myself off of both medicines and have seen no changes in my BG readings. He told me that there is no way I can control this with diet. I have read otherwise. Just wondering if I am crazy for wanting to control this beast by eating right. Thanks for reading and any replies, positive or negative.
