Well thats what I thought would happen, but my admission time was 7.30am, had to get up at 4am as manchester was a 2 hour drive away for me. I went down to theatre at 11.30. Though I’m assuming if they have loads of day cases you will be admitted later in the day. There were 3 other girls being admitted when I was, hope that helps. Whens your op? Where you having it done? Good luck
