Hi demi Wanted to check up on you

If your still not better I thought perhaps you ate a kind of food that your body is not used to? for instance if you ate greasy food and your body is not used to dealing with greasy food it basically doesn't know what to do with it it's like trying to deal with a foreign substance that it doesn't know how to break down but as others have said it also could be exhaustion or dehydration ect.
Honestly I would take some tums and eat soft food like soup and crackers for now
