Hi all.

I have a friend, female, 60, who has a gastroscopy appointment next week, and doesn't know whether she should have sedation, and if she doesn't have it, should she go with someone anyway. She doesn't have any family nearby so I've offered to accompany her if she wants. 

If you've had this procedure please can I have your opinions about whether or not sedation is important, and whether or not she can go unaccompanied. Thanks in advance.
