Sorry for late reply and inconvenience.
Thanks for all this additional information.
I understand your concern.
Well as you describe, it sounds like viral gastroenteritis.
I would recommend trying over the counter Liquid Emetrol every 15 minutes to settle vomiting.
Take OTC Peptac liquid (contains alginate) 500ml or Zantac.
Hydrate yourself with Dioralyte oral powder sachets.
Start probiotic and Metamucil.
Eat easy to digest food like soup or BRAT diet (bananas, rice, applesauce, and toast).
Take OTC Imodium if you have severe diarrhea.
Take proper rest and avoid dairy products, caffeine, alcohol, undercooked meat and fish and fatty rich food.
If your symptoms will persist you need to be seen by your regular doctor for a clinical examination ASAP.
Let me know if you have any further query so we can discuss it thoroughly in every aspect.
