Urgh, poor you sounds grim. Please don't go to work tomorrow! If you pass it to a child they are very likely to then pass it through the family. No-one is going to thank you for that the week before Christmas!
Keep drinking water and eat very plain food little and often. Hope you feel better soon
Dh had the same illness last week. After 5 days he went to the GP who told him to eat dry toast, & drink flat lemonade for energy. Also to take Diorylte to replace lost fluids. He was unwell for a week. Hope you feel better soon.
