Hello and thanks for trusting me to help you. I am a board certified consultant with over 30 years of experience.
I understand your concern.
Well as you describe there may be possibility of Viral gastroenteritis in your case.
You are doing good to rehydrate yourself with plenty of fluids and Oral rehydration solution (Gatorade).
Also take metamucil.
Continue to eat easy to digest food like soup or BRAT diet (bananas, rice, applesauce, and toast).
Yes you can take OTC Imodium now.
Also take OTC Motrin for pain and fever.
Take proper rest and avoid dairy products, caffeine, alcohol,undercooked meat and fish and fatty rich food.
Start a probiotic and eat yogurt.
If your symptoms 'll persist you need to be seen by your regular doctor for a clinical examination and undergo Stool routine examination, CT scan abdomen to rule out underlying possible cause which may include Intestinal parasitic infection, colitis, Bacterial gastroenteritis..
Also if you feel dizziness and severe diarrhea then you may require IV fluids and injectable medications.
