Burger & Baked Potato Illness - Wendy's,

I ordered a hamburger meal with a baked potato as a side. .I went home ate the burger.
A few hours later I was hungry again so I ate the potato.
About two hours later I was throwing up, having severe stomach cramps, dizziness, hot and cold and sweating. I was so nauseated and my heart was racing.
It was awful, I was just praying to God to help me feel a little better.After about four hours I slowly started feeling a little better. If not I would have gone to the hospital.
Its been a week and I still feel a little weak from it and am still slightly nauseated. | Symptoms: Diarrhea, Nausea, Fever, Vomiting, Cramps, Dizziness, Sweating, Weakness
