For example. Yesterday I went to eat at McDonalds and after I finished my Big Mac and fries I started feeling nauseous.
This never happened before, just the last couple of months. I also never eat in McDonalds. Just occasionally but I do eat chips and popcorns and such and I get nauseous after eating them.
Can anybody tell me why ?
