I was on Diltiazem for 10 days and felt great. Then pow, I got so hot on my skin, and yet my teeth were chattering. My heart was beating so fast I couldn't count it. I ached all over. I went to bed to warm up, and woke up in a sweat. I stopped taking the pill, but still feel cold, and not myself yet. How long does it take for the med to leave your system? I did have a glass of red wine that day, so don't know if that was the cause. I'm getting nervous about the way I feel. Thanks.
