I got food poisoning again...

This is the third time in a year and at least this time I let myself throw up the last time I didn't want to throw up so I stayed sick for like 3 or 4 days this time I just let myself throw up and I feel better within 24 hours. Good for me but bad for my toilet! any way I don't know what I ate this time. I just know that I cheated yesterday and had my last candy bar and even though I told myself I didn't even like that candy bar. I eat a ton of grapes, a pear, lots of taco soup, lots and lots.
