Hi there. Thank you for your question. I will be helping you out with your queries
There are two main possibilities with the symptoms that you are having:
1. You could be having stomach flu which is also called as viral gastroenteritis
2. It could still be food poisoining even though none of your friend had any symptoms.
The most important thing is that you must prevent dehydration from happening because losing too much of fluids can cause one to become dehydrated
So you need to take lots of electrolyte rich fluids like gatorade or pedialyte
as much as you can
and if you cannot keep anything down and are taking out all the fluids then you will require a trip to the emergency for possible intravenous fluids
are you with me?
any more questions?
If you think you need to go then you should go right away
