I’m on some medication that has a chance to cause serotonin syndrome when taken together though the chance is pretty rare. 

But it still makes me nervous. So has anyone actually experienced serotonin syndrome?

Was it sudden or did it happen gradually?
How did it feel?
What symptoms did you have?
Did you have to go to the hospital?
Was it seriously life threatening?
What medications caused it?

Like I said, I know it’s rare but it’s good to hear from other people’s experiences.
