Dangerous for Kidneys
I did not use it long enough to be able to address its' effectiveness as a weight-loss aid.  In less than a week, I began to have an irregular heart beat, so stopped using it.  In less than a month, I was in the emergency room with atrial fibrillation, pulse rate reaching 160, and terrible kidney function lab results. My kidney tests are still not back to normal after a year.  Please be sure that you have your physician check kidney function if you insist on using Sensa.
