Grrr! I had a long reply typed out and DH's computer logged me out of here!
I haven't read everyone's reply so I'll just share my experience.

I had an interthecal. Same drugs as an epidural just placed higher with an instant effect and shorter life span. You do need your water broken after getting it since it only lasts about three hours. They want to get you in and out.

By the time DD was born I had had the interthecal for all of 10-15 minutes. In that time:
I passed out
Needed to be woken up to push
Needed oxygen
Recieved two bags of medcine to bring my dangerously low blood pressure back to a safe level
DD was born floppy and purple, needed oxygen, and was so tired that she didn't even have enough energy to open her mouth to latch. The only reason she started to nurse was because a nurse helped me out by holding her mouth open and showed me how to express into her mouth. While I did that she tickled under her chin to stimulate DD's swallowing reflex.
We both just exsisted for about a day and a half. I was so out of that I passed in and out, had blurry vision (despite having brand new contacts in) and was dizzy. Both of us were extremely sluggish. So much so that co-cleeping was extremely unsafe for the first couple days.
The tricky thing about these drugs is they are based on weight. If you are off even by a couple pounds it can have reprucussions. In my case I was severely overdosed as was DD since they do cross to the baby. Yes these drugs have their place and can do some good but America over does everything, including this one. Very rarely will you find a women who was totally informed of her choice at the time she made it. It's usually due to a bad reaction that they start the research.
In my opinion the best pain relief is a good support person/system. Especially for first time moms. Find someone who can tell you to shut up and get a grip or whisper sweet things to you. Whatever you need to help you get through it find someone who can help. Someone other than your husband.

Yes they can be a great source of support but (especially if it's a first time birth) they can get wrapped up in the birth and the emotions and movements from it just like you are. IMO it can be unfair to expect hem to keep their head on straight enough to not only be there but to be there as a support system.
I think the other thing is trsuting your gut and knowing your stuff. Yes it's helpful to read 700 pages of what worked for other women but that's what worked for them. If getting in the water doesn't work for you don't do it. I had read so many things about it being so heavenly that when it didn't work I was pissed! I told DH that everyone who had ever said it was good was a liar and just trying to be hippie like and natural minded. Turns out DD was face up (which I think was excaberated by the pain medicine....too speedy a birth plus being tired from the overdose she didn't have the time or energy to turn....which led to an episiotomy and the dr.'s finger prints on her head for two days) and water doesn't really work for face up babies.

If it feels right to you go for it! I think that in the end is going to be your (and everyone else's) saving grace. If you need to do runners lungers by all means go for it!
As for natural minded relief the only ones I know of that come to mind are:
*Hypnobabies/meditation
*water
*moving/not being flat on your back
*low pitched moans (open mouth= open vagina= less tension and more effective contractions)
*sex/orgasm (you can read about it on Laura Shanley's site)
*massage
I'm sure there are more but tha'ts what comes to mind right off the bat.
