I have heard and this was from medical students that were doing surveys on ppl that had an epidural ( 2 days after I had one) that the bigger you are the harder it is to get an epidural in cause they have trouble feeling for the spine if you are overweight, and i know with my SIL it took a few goes and she was overweight at the time

I had an epidural in within 5 mins in my labour with Kam no dramas with it at all. Not sure about adding drugs to it etc though as mine were added straight away and yep it ties you down to the bed you can't go anywhere. Wouldn't be able to feel the floor to walk anyway LOL.
