Seroquel was a great drug for reg depression, however I’ve tapered down from 150mg to 25 mg now, maybe in about a month I will be off. I tried old turkey, but I got brain zaps and hypnic jerks at night. My doc has me on trazadone now. I haven’t noticed any change in my heart issue though. I was hoping that it would get better. Idiopathic heart failure is my diagnosis. Apparently it may have been caused by a virus or some other factors. It is fairly common in the cardiomyopathy community
