I would contact RG and ask for a special formula for your next cleanse.
There maybe other herbs that you can take on an on going basis, like the in between herbs. The in between herbs make a HUGE difference with me, I didn't start them until right before my 3rd round and I noticed an immediate improvement.

Coconut oil is shown to kill certain parasites, I always have bad die-off when I raise my coconut oil dosage. I also eat fresh coconuts...very good if you like coconuts.
I hope this is some help to you.
