question: I was diagnosed with diabetes 3 years ago. Since getting my meds right (Metformin 450 mg x 2 day) my levels have been fine. This past weekend it jumped to 259 Sat and 265 Sun. This morning it was 277 and this afternoon when I got home from work it was 297. I have an apt with my Dr on the 29th, is it safe to wait that long? and what could be causing this sudden spike?
