I was taking Diovan 80mg for about 4 months and was told prior to taking it by my physician that it had little to no side affects. I experiencined a great deal of weight gain, fatigue and bloting. I found it almost impossible to loose weight even with everyday running and dieting. In addition, often heart rate surges during sleep, and great swings in mood/depression. It assisted in bringing my blood pressure down significantly but ultimatley stopped working. I am now on Lotrel.
