I have done it twice. The first time I had to do it twice...but it worked. Yes, it gives u bad cramps and the runs..but thats what makes it work. On the plus side..you wil be so cleaned out..you won't crap on the dr/midwife! Lol! That was always a fear if mine!
If u do it..get the tasteless, odorless kind. U have too be generous with it. A tablespoon or two isint going to cut it..as I found out the first time.
