I'm scheduled for this coming Monday, the 4th. At this point, I'm just impatient, the last 2 weeks haven't been too bad. I haven't really been hungry however, I have been tired and had slight headaches. The biggest problem has been not letting my blood sugars get too low, so I've been testing more frequently. I'm a pretty controlled diabetic normally, but the cues or indicators that I normally get when my glucose levels. are dropping aren't occurring with the pre op diet.
