Can't comment on the epi-no, I have been very fortunate to have avoided any tearing or stitches both births. I did however have 'success' with RLT. I drank at least 3-4 cups a day and gradually increased that as I approached my EDD (I doubt I ever drank as many as 8 though). My first labour was long and drawn out, 72 hours. My second was only 5 from first niggle to birth.

I will say though that my second labour was much, much more intense and I'm not sure if that's a good thing or not!
