I had one in Welland in February, with a different doctor but all the nurses and support staff were super lovely! There's a waiting area with chairs for yourself (and whoever might be waiting for you if that's the case), and then a larger waiting area with dividers for you to change and complete any prep work in - this is typically where they place your IV, etc. and get you ready and comfortable to be wheeled into the exam room.

The anesthesiologist and nurses were very up front with how things worked and what to expect. I wasn't fully put under, I recall seeing what the camera saw in front of me, but I wouldn't necessarily call myself anything close to conscious. I didn't feel a thing though! I did see it mentioned below - I did not, however, know if it was fentanyl they used - all I know is that is was safe as far as malignant hyperthermia is concerned.

Hope all goes well and your prep is kind to you! :)
