So reading various dosage posts and methods for taking NAD I decided to give 300mg a go as it was on the lower side of the IV drip schedule.

I lost my breath and fell to the ground. My vision alternated between my room and white static. After 60 seconds my entire body started to burn and sweat. Truly I thought I was going to die. I tried to call my wife and couldn't figure out my phone.

I woke up 10 minutes later and felt a bit loopy, within an hour I was ok again. Needless to say I won't do that again but I wanted to put this experience out there incase anyone else decides to try this. I'm in pretty good health but I can absolutely imagine that dose giving someone a heart attack.
