Feeling sick after RACE 2008

Somehow or rather, after the dinner at RACE 2008, I was feeling very very sick. I think the food and beverage were not fresh at all. After a photography session on the stage, I rushed to the toilet and guess what? I vomited. My stomach felt damn sick wei. Therefore, could not enjoy myself during that night. All I wished for that night was to go home. Once I reached home, and again I rushed to the toilet and this time, I vomited EVERYTHING. Food poisoning? I have no idea. Could not have a good sleep. Somehow or rather, my body was feeling very hot [though the air-cond is on] and I woke up in a middle of the night a few times. I am feeling better today but still feeling sick
