Well this sucks!

Yesterday I went to the doctors and found out I have type 2 Diabetes.  It is sudden and unexpected as 5 months ago I was in the normal range and not even at the high end. The only thing that has changed is that I went off Cymbalta a month ago and was going off slowly for the last 4 months. I have heard that this happens a lot with people going off Cymbalta. The doctor put me on Metformin but my levels still seem to go up 2 hours after meals. I know its just been a day but I am literally starving myself for fear of eating something that will make it go higher still. I am only slightly overweight (20 lbs). Has anyone else had this happen when going off Cymbalta? Were you able to get your levels down?
