To those who don't know what I'm talking about. It feels like energy draining down out of your body, maybe like going down really fast on a rollar coaster. It's very hard to move or talk while this is happening and it usually only lasts for about 5 seconds.

I thought this happens to all smokers but I guess I'm wrong. Some things I hear about it is -

Ego death
Letting go of attachments
The little death
The fall to hell
The path to truth
A shower from heaven

I wonder what is physically and mentally happening to me, I'm sure there has been some research on this. I also wonder on a spirtual level what is happening.
