My girlfriend and I, have eat something that made us feel bad. We have chills, nausea and vomits during the night after having dinner. We think it was indigestion. We'd like to know the best diet in these situations and if to drink milk is good or bad. If you were nauseated or vomiting, milk would not be good to drink.
Milk can also aggravate diarrhea.
Generally, no food is better until you quit feeling nauseated or vomiting for an hour or two because whatever you eat will probably come back up. If you vomit or have diarrhea within a few hours after a meal, I would suspect food poisoning. You may have eaten food that was undercooked or food that was cooked by someone who was ill himself or herself. Food poisoning can be very dangerous. I do not know why you would have had the chills, ask your doctor.
