First time on LSD and getting waves of nausea?

Hey everyone. So I've noticed I've been getting waves of nausea and can't understand if this is normal, which I'm sure its not, or something I'm doing to myself that like a form of anxiety? And yes it was tested with a regents tests and it showed as good.

I dont suffer from anxiety AFAIK but I think this is how I feel. Hot and cold with hot and cold sweats, clammy feet and hands and a slight increase in heart rate. I kind of feel like this is something I'm doing to myself somehow but I dont know why?
