I have a procedure I have been waiting for months to have.
The pre assessment nurse was insisting that I must have someone to collect me (because of the sedation). They need to collect me from discharge lounge and sign me out.
What happens if I just walk out (to my taxi)
I don't have a support network yet. Moved here not too long ago. Various reasons. Anyway, my H cannot drive to get me at that time as he can't drive right now. His epilepsy has come back
Obviously I won't drive myself. But what happens if I just walk out and get into the taxi? Will they call the police or report me for safeguarding concerns? 
Taxi will be ££££ so no my H cannot come and collect me inside. He will need to be home for our disabled DC who cannot be taken out without my car etc
I just don't know what else to do. I am desperate to have this done
I have had this type of sedation before (NOT GA), for something else. I felt a bit sluggish and woozy for a while but that was it so I feel confident to just get a taxi, who will drive me to my door where my H will greet me and stay with me for the 24 hours they've asked
