Hey Megan, I had my op last Tuesday and my admission was 1pm too, I got taken down to theatre about half 5 then left hospital at half 9. It’s not too bad was just really hungry and fed up of waiting but was worth it in the end!! just take lots of magazines or something to keep you entertained I would advise getting up early to have some breakfast before you have to stop eating, good luck for tomorrow 🙂 xx
