I took the Januvia samples my doc gave me for 3 weeks before I saw any difference at all. Apparently, it takes that long to manifest itself. It never said that in any of the research I did on it. The last few days I have really pushed it to the limits eating things that I knew had made my blood glucose soar to over 200. Now, I can't get it to go that high no matter how much or what I eat. That makes me happy because it is when BG goes high that damage is done to internal organs.
