Re: Does anyone know what could have caused this to happen. Very scary :/
It could be a few things.....depending on what you were talking about or thinking, it could have been anxiety.
Did you have any alcohol or take any new supplements?
Was it very hot and humid in your area? and were you in a non-air conditioned house?
It's also possible that your blood pressure started to lower causing you to feel nauseated and weird.... then when you stood up it shot up causing you extreme symptoms.
Could you possibly be pregnant?
You should go see your doctor regardless and explain what happened so that you can be checked out thoroughly. I can relate to those symptoms. I once took a niacin tablet that was way too high in the dosage and the symptoms were exactly as you described. But, I've also had the same symptoms when my blood pressure dropped, as well as when I've had anxiety/panic attacks, when I've not eaten for a while or when I've had too much coffee without eating....
So, while it can be varied in the reasons.....what exactly happened to you should be examined seriously.
Please let us know what the outcome is.
It's all a matter of perspective!
