I ate just a couple of bites of the chicken and rice dish?!
Answers:
Normally spoken two bites can't really hurt you.
But if you feel nausea or just a little sick then you should keep an eye on it and if it doesn't get better, I would go to a doctor if I were you. Just sleep on it :)
If the chicken was cooked thoroughly when it was cooked the first time you have less chances of getting food poisoning. If the food wasn't molded or left out for a long time before you reheated, and ate a few bites, you should be just fine. Especially since you had very little of it.
I don't think you'll die unless somebody laced it with cyanide
Don't worry, you won't die just yet; maybe tomorrow!
