Januvia and medications

I started taking several medications along with Januvia in January and had mild depression it stopped after a week to two weeks. Because of some miscommunication with my Dr. I went of of januiva for about 1/2 of a month. On March 24 I started taking it again and started felling the mild depression again along with several other side effects that were common. I had one pharmacist tell me it was a side effect another that said no way and yet another that told me that if i had mild depression with it once that i problem was a side effect even though it was not common. Has any one at all had any sort of depression. Please i must know.

I've been taking Januvia for 8 weeks, and have experienced muscle cramps with shock-like pain running down my leg into my heel; upper and lower GI spasms; night sweats with sleep interruption; and I gained 5 pounds in the first 4 weeks which I can't attribute to anything else. I've also taking metformin and glyset for several years, and although I've experienced the night sweats, they've greatly increased in intensity.
