Hi Lonestar5212. I was banded on Monday, 10/22, and am also diabetic. I had no problems with the preop dieting. I did fine the day of surgery - it fact my blood sugar was high all day. Tuesday morning, though, mMy blood sugar dropped to 56. Since my doctor had said no fruit juice because of the acid, I tried some milk (skim milk does have sugar in it). When I rechecked 15 minutes later, I was at 51, and the surgeon said to go ahead and try orange juice. The juice caused some stomach upset and didn't sit too well, but it did work. The surgeon made some adjustments in my medication, and I'm checking my glucose levels frequently at home. I think you just have to be vigilant and monitor very closely. Have you talked to your doctors?
