There are many issues that could contribute to your symptoms, and I 'm not a doctor, nor play one on the Internet, but after reading your history, you should be aware of a little known type of diabetes that is becoming more common in adults. Called LADA, or Type 1.5, it is slowly progressing and takes a special protein antibody test to find, since it is an auto-immune version. http://www.everydayhealth.com/diabe...5-diabetes.aspx As mentioned before, you could first start easily taking your own BG to see if you even have high numbers, both fasting and after eating at home. Even if your morning fasting number is OK, also take it after eating beans or potato to see how high and how long until back to baseline. Both the WheatBelly article above and this one http://chriskresser.com/how-to-prev...disease-for-16/ explain the process (I get a meter and 100 strips for around $20 from an on-line diabetes supplier)
