I not long ago got back from hospital after overdosing on sertraline, taking a week of my prescribed dosage at once. I am okay, apart from some tachycardia, dizziness and disorientation. My heart rate went from 150 bpm to low/mid 90s now, occasionally dipping into the 100s.

My mother said to me that I had a good chance of ending up with cardiac arrest, which thankfully didn't happen. 

Thanks for everyone who commented on my last post.

To those thinking of overdosing, please don't - it's not worth it.
