Januvia and cholesterol

I have been experiencing the following side effects after taking Januvia for the last year. Night sweats, nightmares, GA (which is fatty tumors on my left forearm I have about 40 of them), arthritic type pain in my left shoulder and left hip that radiates down the arm and leg. eczema on both hands SEVERE. I have quit taking the blood pressure medicine (used only as precautionary) cholesterol meds, and prozac for a week now and am very sternly watching my diet!!! and exercise regularly, I have yet to quit my diabetic medicine but will quit one at a time to figure out which is causing my side effects. I believe the drug companies are making a killing off all these drugs that make me feel like crap. I am taking more herbs, vitamins and like I said eating HEALTHY. I won't even use splenda or sweet and low, Have been using Stevia if I use any sweeteners at all.
