I have a suggestion for you, just as a little icing on the cake.
Try, the morning of the day you start flushing, to take 60ml of Castor Oil and 100ml of Orange Juice (shaken for 5 minutes). You will have to hang around the bathroom all day. Then that evening take your oo/gf concoction.
I took the concoction twice. The first time I got pots full of reddish things out. The second time I took it (my next flush) I got pots and pots of liver flukes out. I was shocked and had to stand in amazement at the toilet looking at all those beasties that were in my body and I didn't have the faintest idea they were there. My son did a flush with the Castor Oil mix and got the same results as my first time. He is going to do it again his next flush to see if he gets any flukes out too.
