Same here!! But, before I go on....I know many many many people who have had them done and don't remember/feel a thing.
Mine was years ago and lets just say, not a happy experience. The thing that ticked me off is that they didn't believe me when I was "trying" to tell them the "drugs" were not taking effect...instead they strapped my arms down to the bed!!
Afterwards in the recovery room, surrounded with a bunch of sleeping patients (like I should have been), my nurses were calling everyone in to "look at me" since I was up and alert and lets just say a little PO'd!!...As they told me....I was an EXTREMELY rare case with this happening.
Since then, I have had 2 epidurals with my 2 kids that didn't take either...so it must be me and pain drugs or something
I don't mean to scare you but this is my experience...I am sure you will be fine....my mom has one done every 6 months for the last many years due to alot of stomach/esophagus problems....doesn't phase her in the least.
Good luck...relax...you will be just fine!
