@happyme get some peppermints and ginger tea. Ginger is an anti-emetic so it stops vomiting/makes it impossible for you to phyiclaly throw up, peppermints combat nausea so will stop the sick feeling. IT will be from the GA, a lot of ladies suffer from this, they give you anti sickness meds whilst your asleep which is why you would have felt ok yesterday, the GA stays in your system for a few days x
