anxiety
"I suffer from anxiety, low mood, and Cardiophobia. I started on Citalopram which affected my heart (palpitationss, racing, etc.) and so stopped taking it. Next in line was Sertraline. Although this medicine had no side-effects, neither did it help my anxiety. I am now on Mirtazapine 15mg nightly. 1st tab I felt like a zombie with bad headache but anxiety symptoms disappeared like magic. 2nd tab I started to feel the palpitations creeping slowly back and just prayed that it was due to the anxiety, although I felt much better. Took 3rd tab tonight and the palpitations are definitely back with a vengeance, I feel really groggy and clumsy. I hope the palpitations will decrease over time as this medicine is great for anxiety although no point taking them if they make heart-related anxiety worse."
