Food Poisoning...please help me!?

I suspect I got food poisoning on Sunday night. I had order a sausage pizza from Subway. Within a couple hours I started to feel sick to my stomach and had some diarrhea. Within an hour of coming home I was vomiting. I must have thrown up like 15 times. It has been about 3 days now and I feel much better but my stool is a liquid yellow with some solid bits in it...I am sorry for being graphic. Is this okay? When will I start to feel normal...I hate it. I have been trying to have milk and yogurt and apple sauce and lots of ginger ale. I have not thrown up since Sunday. What should I be eating?? Any suggestions on what I should be doing? I just want this to go away. Thanks so much.
