Last Saturday (5 days ago now) I had a really busy day and was in a right kerfuffle and I accidentally took too much of my Quetiapine. Realised and immediately freaked out, went to hospital and they monitored me. It was me extremely drowsy and sleepy but the Dr said it's hard to OD on Quetiapine anyway, my blood pressure, pulse, ECG and blood results were all normal and I was sent home after a night in A&E. However last night I kept having nightmares and I kept waking up with my heart POUNDING, like literally so hard and noticeable and I've had it all day today and now I'm SERIOUSLY scared that I've permanently damaged my heart in someway by taking too much?! Please help I'm so scared
