Throwing up can’t keep anything down (Male, 18)

Yesterday, I ate a Chick-fil-A Deluxe chicken wrap from a fancy gas station and Blue Sour Patch Kids while on vacation. We came home the same day and I was fine, but the next morning, after showering, I started feeling cold and nauseous. The symptoms gradually worsened, and by the afternoon, I vomited with light green vomit. I thought it was over, but I vomited again, having only eaten three small crackers. I went to lie down at a 45-degree angle because I read that lying down while sick is bad, and I fell asleep. About an hour later, I woke up vomiting again, followed by green diarrhea.

Time line

12pm ish first vomit

1:24 ish second vomit

2:26-ish third vomit

As I'm writing this it is 2:46 I feel fine now but that's what I thought before what do I have? Should I just tough it out and try to drink water?
