i just had a colonoscopy done the other day ( same as an endoscopy but the camera goes in from the other end!) i reminded them about my allergies and was given the choice of having gas and air through a mask instead of having the iv sedation. (the sedation is not a problem for me, but the sticky patch they put over the iv to keep it in place is as it blisters my skin like a burn.
they say you must have someone with you for 24 hours after the procedure...as i live alone with no family contact, my carer and i said she was going to stay but when she settled me back home she went home..i am capable of calling for help if i need it!
also you are not meant to drive for 24 hours, not even a mobility scooter...yeah right my scooter is my only independent way of going outside. i did feel tired but often do regardless of sedation and still drive scoot, only difference is that when i feel tired i do not drive it on the road or go too far.
