high blood pressure
"Was taking 180mg for 2 weeks and was not getting a decrease in BP. Was really no difference from not taking any meds.  I had heart flutters and body aches where I thought I had one of the worst fibromyalgia bouts ever. Doctor doubled my dose. In one week the body pains/aches worsened, my blood pressure went up, and my heart flutter worsened. Also gave me headaches and my nails have never grown so fast in my life! 1st day off Dilitiazem and my body aches are already going away as are the heart flutters. 3 weeks of unsatisfactory treatment and would not recommend this drug to anyone. Going to Atenolol."
