Hi, posting for traffic. Have a colonoscopy booked for tomorrow and the clinic (private provider outsourced from NHS) only emailed me an info leaflet last thing this afternoon outlining the (relatively high) risk of perforation, the option to be sedated, etc.
It doesn’t explain on what basis you might decide to go for sedation – it just says some people do and it’s your choice 

So wondering how uncomfortable/painful it is, if sedation helps with with, if other painkillers are advisable, etc.?
Also, if damage does occur, what the long-term implications of this are?
Feel a bit cross to be honest as I would have liked to discuss this with someone like my GP, however seeing as it’s tomorrow, if I cancel it might be another month or so before I can get an appointment again.
Any info or experience appreciated.
