I Had Food Poisoning A Couple Days Ago But The

I had food poisoning a couple days ago but the next day I felt better then the day after that I woke up feeling nauseas and had loose stools again, then the next day I was fine all day and then I had wings and French fries and a diet coke for dinner and it made me so sick again I couldn't control my stools and they were very loose and now it's continuing on to today, I have only had a sip of Gatorade and I had to go to the bathroom again. I don't know if it's my body still not over the food poisoning or something else
