Zithromax Z-Pak and low blood sugar

forgot to add with my first post-- have been off the med now for about a week and a half, the low blood sugar sensation persisted for about four or five days after stopping the med and I have a white tongue that is most uncomfortable and getting worse, sore spots in mouth and throat. Wondering if I have thrush...

hypoglycemia? Not a diabetic, but had reaction similar to "hypoglycemic" reactions my doctor said I had during pregnancy during which time I had "borderline" gestational diabetes. Feeling of shakiness, somewhat weak, some difficulty getting words out. Had to pretty much eat many six small meals per day and even snacks and would still get that shaky low blood sugar sensation.
