Is it normal to feel this ill and then crave cheese?
So the title is weird but please allow me to explain. Sometimes, not very often, I'll do something that requires a lot of moving (energy I guess?) like today, I changed my bedsheets. Before this, I'd eaten dinner a few hours before and then about an hour before changing my bedsheets, I'd eaten a chocolate bar. Let's get to the point, I'd eaten fine and then changed the bed when suddenly I felt really sick. Like, the vomit was coming up but I couldn't be sick; kind of like acid reflex. Then I started shaking and my legs were shaking badly. I went to have a shower and the world started to spin and everything was kind of weird looking and I just felt really weird overall. My stomach felt heavy and I still felt sick, then after my shower I was really out of breath and my hands and legs were so badly shaking that I had to get into bed in case I was going to faint. Then after a few minutes, I just really started craving something with cheese in it, specifically a cheese sandwich. I should mention that sometimes this happens even when I'm not moving around. Is this normal and can anybody tell me what the hell is going on?
