Hi,
I was diagnosed w/ diabetes 15 months ago and put on Januvia. I haven't had any side effects from it and have done very well w/ it. I try to take it at the same time everyday. I was taking it before bed, but now I try to take it at lunchtime. My dr. says it doesn't matter when I take it - just take it at the same time. I tried metformin but did much better on Januvia.
Good luck to you.
Becky
