31 weeks and 5 days with Food Poisoning

Yesterday after a family funeral my family at a Mexican restaurant that ended me with throwing up and diarrhea since last night to today. Went to hospital last night got out at 7 am and felt better but as soon as I left ,I felt sick again. Been throwing up non stop with non stop diarrhea. Haven’t been able to keep anything down, finally got my prescription for nausea and vomiting and ate some no sugar jello after. Been burping it up nasty like I’m going to throw up still. Any ideas on what’s best to drink or eat?
