If you’re worried, keep a paper bag nearby, when you feel like that again just take a few slow breaths into the bag, it will help regulate the oxygen level and stop the hyperventilating and dizziness. I found the side efects of the anaesthetic were everywhere, I felt very out of sorts and people just said to me that the ga can really knock your body out for a while. It’s very weird! Hope you’re feeling better soon, same to you as well kerryj x x
