Quoting Mama to William + 1:" I hope you're right. I really don't want to get an epidural again and it seems like everyone gets one after starting picotin. Ugh."
I didn't and my son was posterior too! It was really tough plus I'm a wimp, so if I can do it - you can too.
Make sure you let all the midwives know to not offer any pain relief and if you ask for any for them to provide you with alternatives and support before acquiescing to your request .
e.g. You say "I want an epidural!" they say "Move position, take a shower, let's try counter pressure, you're doing great, baby will be here soon" etc. etc.
