re: What is the longest you have gone without sleep?

Approximately 90 hours once. Due to an episode of extreme anxiety. I had tachycardia, mild chest pains and restlessness for 4 nights. Never hallucinated, but felt myself losing my mind which was very real and terrifying. There's a point of no return and I was getting there. The doctor gave me like 150mg of Sertraline. I finally took a nap that evening for 3 hours. Everything went back to normal pretty fast after that.

Scariest thing I've ever gone through.
