Hi there - I had a gastroscopy in June and was very nervous about it. I have to say it was absolutely fine - I had sedation and throat spray and afterwards, I really couldn't believe how worried I had been over nothing! The sedation allowed me to have a hazy recollection and there was certainly nobody holding me down - the sedation is very calming and I just laid there and did as I was told! They only take 10-15 mins. You'll be fine! Also, Midazolam isn't the "date rape" drug and wears off really quickly - I felt back to normal as I left theatre.
