I am taking amitriptyline and buspar. It believe it is the anti depressant, but I have been noticing my heart pounding so much. It gets bad and I can t get it under control. I lay here and I can feel it and it feels as if my heart is too big for my body. I am on the 75mg. I had a anxiety attack yesterday and my heart was racing. I felt as if I couldn t get it under control, having other things on my mind, and I had to lay down, take deep breaths. I got it under control after a while. Is there anything to help with the heart pounding? Maybe lowering the dose? Trying a different one? I ve only been on it for 3 days. I did not take it tonight, but right now, my heart is pounding and I can not go to sleep. Please help.
