Hello,
It seems that you have had a bout of food poisoning.
Nausea with loose stools are classical symptoms of gastroenteritis .It usually is bacterial .Recurrent diarrhea also causes dehydration and symptoms like dizziness and cold extremities.
1) Start a broad spectrum antibiotic like Tab amoxicillin to prevent the progression of infection.
2) Go to the nearest laboratory and get a blood culture done to rule out sepsis. Also get a complete blood count. Based on the culture sensitivity the antibiotics can be changed.
3) Increase the intake of water and other fluids to prevent dehydration. If you cannot take enough fluids orally, I would suggest you get yourself admitted in the hospital and take I.V normal saline.
4) Check your temperature regularly and maintain a record to check the progression.
5) I advise you to not take anti motility drugs like lomotil, because taking anti motility drug increases infectious agent in your intestine.
If the severity of the symptoms increases kindly consult a doctor for the aforementioned recommendations. It's also important you take measures to prevent acquiring an infection in future.
Thank you.
