Paula I think you have lots of answers here.

For all my EPU I have been put under a general nad back to work the next day. The recovery room is just to make sure you are Ok to go home and in my case sandwich time after fasting. Mostly after my EPU I have been up and ready to go after an hour or so or me realising I am awake. Last time I had to wait for DH as he had not had his TESA yet.

Ask all the questions you can sweet
