This Past Thursday Morning About Two Hours After Breakfast I

This past Thursday morning about two hours after breakfast I suddenly became sick to my stomach and within five minutes I was vomiting. I was on the bathroom floor for two hours either vomiting (four times), or too dizzy to get up. I was having hot flashes on the inside and cold sweats on the outside. I was white as a sheet on my face and the sweat was pouring off of my entire head and neck. My skin felt cold and clammy. After two hours of this, I was able to make it to my bed and I crawled under the covers for two hours and then got up and felt almost normal. I went back to work. Several people had the same breakfast as me, so I don't think it was food poisoning because I was the only one who got sick. Something similar to this happened to me about one year ago but not quite as severe. I think this was a healing crisis, what do you think?
