The other day I was smoking a shitload. It was kinda cold outside and I was shivering like crazy. Thing is, it wasnâ??t even THAT cold, and even when it is, I hardly ever shiver, maybe just like my jaw a little. This time it was like a full body shiver and one that I couldnâ??t control even if I tried. Going inside and getting warm did stop it though.

Is there any chance this is what happened to you?
