Other medications before epidural??

So this is my second pregnancy, I'm 36+4 weeks and with my first I had gotten the epidural. Judge if you want but back contractions are no fun. I'm however wondering how well they worked for other moms, and what it was they got? I wanna hold off on it as long as possible that way this time I'm not puking for an hour on and off everytime I hit the epidural button after having it so long.
