I had just gotten over food poisoning. this was the first time going through something like this so if you don't know how it feels well basically it starts out with you being really cold like even if its a little warm in your place this right away can be a symptom of food poisoning then after the cold feeling you get a fever to where you still feel cold but your hot at the same time also you get a sour stomache due to the bad food you ate. IMPORTANT! do not stop yourself if you have stomache problems just let it be because my issue was taking over the counter drugs like alka selzer n stuff like that it only prolongs it so just let it be :) you should be fine within 48hrs or so. So remember to drink lots of water and eat fiber also to not panic and wait it out you should be fine again to enjoy some good tasty food again.
