Ok, heres my story, I have been on Diovan 80 mg for the last 4 years, and on Feb1st onwards I have been on a weight lost regime, taking Niacin and Vitamin C with Diovan, last Wednesday, I went to see my cardiologist and ask him if I can quite Diovan and he has advise me to stop for 1 week and monitor my pressure, my pressure has been going up from 155/100 and sometimes as low as 129/80, this while taking Niacine and the Vitamin C, my question is, is the high blood pressure due to the Diovan rebound?
