First time marathoner experiencing food poisoning symptoms. Tips and advice?

As the title states I have been experiencing food poisoning symptoms since Wednesday. I’ve been having diarrhea (4-7 times a day) and stomach pain feeling like cramps. I can’t defer my race because I did 9+1 this year for next year’s entry.

I feel like I would still be able to run but would have to sacrifice my time goal since I am worried about having to constantly use the restroom.

Looking for any tips and advice for someone that’s been in a similar situation.
