I've been able to mentally make myself sick once...
In fact, it just happened yesterday. I was doing a mental exercise, where I was visualizing the hemispheres of my brain swapping sides to try and turn on my right hemisphere only, and for a few seconds, it felt like the back of my skull was tingling, and that I was about to throw up..
It was fucking insane.
Also, I have a fast metabolism, so whenever I don't eat within about 5 or 6 hours, my stomach churns upon itself. I get lightheaded, I stagger, I slur.. It really sucks.
And the best part is? If I still do not eat, I get diarrhea.
