I don't think so, but I remember the moment it happened. That day I was feeling more stretched and tired than I've ever been. It was the last day of university before spring break. Then my parents started pressuring me over my recently declared non belief in Christianity, and I felt like something in my "spirit", just broke or snapped in that moment. It was clearly defined instant in time where I was completely changed afterwards. I don't remember if it was like a physical pop, but I knew as soon as I felt it that something in my brain had just dramatically changed for the worse.
