| I work in a lab, I've logged my numbers over the years. There was a very gradual increase in FBS for me. Actually, upon diagnosis I was 299 fast... 6 months prior I was in the 110's.
Basically, you should use it as a warning sign IMO. I wish I did. Just start eating right, cutting back on the "bad" carbs such as pastas, breads, potatoes, rice, sweets, etc. Not eliminate, just cut back and see how things go. Your pancreas is probably starting to work a little bit heavy right now to keep your sugars in line, not extremely hard, but harder than it needs to be working. Give it a break, let those beta cells regenerate.
This is just my opinion obviously.
My personal belief is that regardless of what we are told, a fasting in the 100's is a definite warning sign and NOT normal.
