I had 3 out last year. Went under, come too with a load of gauze in my mouth and felt ok Bit achey but otherwise good. I took 2 days off work to recover but prob could have gone back next day tbh

Suppose it takes different people in different ways One thing tho, they wont let you go unless you have a pee (at least here that is) but dont do what i did and down a big bottle of water when your wheeled back to the ward because it ended up all over my blanket 5 mins later and not thru the normal course
