I think that whenever your sugar starts to rise past a certain point, the Januvia works to keep it stable- it doesn't matter whether it's because of Dawn Phenomenon, too many carbs, stress, or medication. That's how it's been working for me.
I've been running a cold all week and my fasting has not been above 107 - usually when I'm sick it goes up into the 120's-
I have had no side effects form Januvia- the package insert says flu -like symptoms, congestion and such, but I never got them. When I first started it, I felt very happy- almost as if I had been depressed and it lifted ( I wasn't) and I think I read somwhere that it may have an antidepressant type effect because it affects those receptors in the brain, but I don't have the links on this computer.
Overall, it's been a great drug for me. Keep me posted on how you're doing with it.
