A year ago I could have written this! Except for the wanting to do it awake part
Anyways, I had a big fear of getting sedation. The part I didn't like is related a lot to my anxiety: losing control! Anyways, I worked myself up a lot before and was even crying in the little waiting room before I went in because I was so scared. Long story short, the nurses and doctor were very calming and they will give you something to relax you before they do the actual sedation. This makes you just feel very sleepy and relaxed. For me, they kind of talked to me a little and I would kind of respond but was drifting off to sleep. Next thing I knew I opened my eyes and it was all over. Oh and I felt REALLY good
It's hard when people say to try and calm down because anxiety doesn't work that way, but believe me, it's an easy procedure and the sedation is a breeze and worth it! Definitely don't think you want to do that awake!
