Welshgirl, I was very sick during the caesarean as well. I vomited 3 times whilst Jacob was being born actually. It was awful. The anaesthetist told me it was due to my blood pressure dropping. The first time I told him I felt sick, he told me that it was normal but that it was unlikely and quite rare that you would actually vomit and at that point I said "I'm going to be sick" and he promptly put a surgical tray beside my head LOL!! I was shaking quite violently for around an hour after the procedure as well.
