Good idea Lori I agree, I did that too the first time around (asked for peth and gas) and yes: it only made it worse. By the time I had my third I resolved to try to avoid all that and I found that my body compensated naturally by actually giving me far superior natural "relief" in the form of longish periods of pain "lull". Just before transition I found that my body actaully gave me a break... it was weird... I felt tired but the pain really subsided and gave me a good half hours break just before it came time to push. I suspect that taking all that "pain relief" in my first two labours interfered with this process. Let me tell you it was very surprising, and very welcome!
